, beheld the crumbling St. Louis riverfront area and envisioned that building a memorial there would both revive the riverfront and stimulate the economy. He communicated his idea to mayor Bernard Dickmann, who on December 15, 1933, raised it in a meeting with city leaders. They sanctioned the proposal, and the nonprofit Jefferson National Expansion Memorial Association (JNEMA—pronounced "Jenny May") was formed. Smith was appointed chairman and Dickmann vice chairman. The association's goal was to create:

Many locals did not approve of depleting public funds for the cause. SaLees, Smith's daughter, related that when "people would tell him we needed more practical things", he would respond that "spiritual things" were equally important.

The association expected that $30 million would be needed to undertake the construction of such a monument. It called upon the federal government to foot three-fourths of the bill ($22.5 million).
The suggestion to renew the riverfront was not original, as previous projects were attempted but lacked popularity. The Jefferson memorial idea emerged amid the economic disarray of the Great Depression

It first convened on December 19 in St. Louis, where members examined the project and its planned location.

Meanwhile, in December, the JNEMA discussed organizing an architectural competition to determine the design of the monument. Local architect Louis LeBeaume had drawn up competition guidelines by January 1935. On April 13, 1935, the commission certified JNEMA's project proposals, including memorial perimeters, the "historical significance" of the memorial, the competition, and the $30 million budget.

Land acquisition, opposition, demolition, and early railroad negotiations (1936–1939)

Using the 1935 grant of $6.75 million and $2.25 million in city bonds, the NPS acquired the buildings within the historic site—through condemnation rather than purchase—and demolished them. By September 1938, condemnation was complete. The legality of the condemnation was subject to many court cases and culminated on January 27, 1939, when the United States Circuit Court of Appeals

 ruled that condemnation was valid. $6.2 million in sum was distributed to land owners on June 14. Demolition commenced on October 10, 1939, when Dickmann extracted three bricks from a vacant warehouse.

Led by Paul Peters, adversaries of the memorial delivered to congressmembers in Washington, D.C., a leaflet titled "Public Necessity or Just Plain Pork". The JNEMA's lawyer, Bon Geaslin, found that the flyers did not taint the project but motivated congressmembers to find out more about the project. Although Representative John Cochran wanted to ask Congress to approve more funds, Geaslin believed the association should "keep a low profile, maintaining its current position during this session of Congress". He advised the association to "get a good strong editorial in one of the papers to the effect that a small group of tenants ... is soliciting funds [to fight] the proposed improvement, and stating that these efforts do not represent the consensus of opinion in St. Louis ..., and pointing out that such obstructions should be condemned".

Congress's reduction in spending made it impossible for the allocated funds to be obtained. NPS responded that the city would reduce their funding if the Feds did. It also advanced that the funds were sanctioned by an executive order, but superintendent John Nagle was cautious: what "one Executive Order does, another can undo". In March 1936, Representative Cochran commented during a House meeting that he "would not vote for any measure providing for building the memorial or allotting funds to it". Geaslin found Cochran's statements to be a greater hindrance to the project than Paul Peters' opposition, for Congress may see Cochran's opinions as representative of public opinion.

Peters and other opposition asked Roosevelt to rescind Executive Order 7253 and to redirect the money to the American Red Cross

When Ickes declared that the railway must be removed before he would allocate funds for the memorial, President of the St. Louis Board of Public Service Baxter Brown suggested that "a new tunnel ... conceal the relocated tracks and re-grading of the site to elevate it over the tunnel. These modifications would eliminate the elevated and surface tracks and open up the views to the river." Although rejected by NPS architect Charles Peterson

The idea of an architectural competition to determine the design of the memorial was favored at the JNEMA's inaugural meeting. They planned to award cash for the best design. In January 1945, the JNEMA officially announced a two-stage design competition that would cost $225,000 to organize. Smith and the JNEMA struggled to raise the funds, garnering only a third of the required total by June 1945. Then mayor Aloys Kaufmann

 the remaining $40,000 in May 1946. By June, Smith found others to assume portions of his underwriting, with $17,000 remaining under his sponsorship. In February 1947, the underwriters were compensated, and the fund stood over $231,199.

 advised Saarinen to change the bases of each leg to triangles instead of squares. Saarinen said that he "worked at first with mathematical shapes, but finally adjusted it according to the eye." At submission, Saarinen's plans laid out the arch at 509 feet (155.1 m) tall and 592 feet (180.4 m) wide from center to center of the triangle bases.

On September 1, 1947, submissions for the first stage were received by the jury. The submissions were labeled by numbers only, and the names of the designers were kept anonymous. Upon four days of deliberation, the jury narrowed down the 172 submissions, which included Saarinen's father Eliel

The family celebrated with champagne, and two hours later, a competition representative called to correct the mistake. Eliel "'broke out a second bottle of champagne' to toast his son."

They proceeded to the second stage, and each were given a $10,000 prize. Saarinen changed the height of the arch from 580 feet to 630 feet (192 m) and wrote that the arch symbolized "the gateway to the West, the national expansion, and whatnot." He wanted the landscape surrounding the arch to "be so densely covered with trees that it will be a forest-like park, a green retreat from the tension of the downtown city," according to The New York Times

 that the finalists and the media attended, Wurster pronounced Saarinen the winner of the competition and awarded the checks—$40,000 to his team and $50,000 to Saarinen. The competition was the first major architectural design that Saarinen developed unaided by his father.

On May 25, the United States Territorial Expansion Memorial Commission endorsed the design. Later, in June, the NPS approved the proposal. Representative H. R. Gross, however, opposed the allocation of federal funds for the arch's development.

The design drew varied responses. In a February 29, 1948, The New York Times

[T]his particular accusation amounts to the filthiest smear that has been attempted by a man highly placed in the architectural profession in our generation." Wurster and the jury refuted the charges, arguing that "the arch form was not inherently fascist but was indeed part of the entire history of architecture." Saarinen considered the opposition absurd, asserting, "It's just preposterous to think that a basic form, based on a completely natural figure, should have any ideological connection."

By January 1951, Saarinen created 21 "drawings, including profiles of the Arch, scale drawings of the museums and restaurants, various parking proposals, the effect of the levee-tunnel railroad plan on the Arch footings, the Arch foundations, the Third Street Expressway, and the internal and external structure of the Arch."

Railroad agreement (1949–1952)

There were several plans for the relocation of the railroad. The so-called La Beaume-Terminal plan, opposed by Saarinen and the NPS, proposed "three tracks on a contained fill along the lines of the elevated tracks." The Bowen plan and the Bates-Ross plan recommended that a tunnel enclose the tracks, which would cross the memorial site diagonally. Saarinen warned that should the railroad be located between the memorial and the river, he would not architect the memorial. The Levee-Tunnel plan, proposed by Frank J. McDevitt, president of the St. Louis Board of Public Service, proposed to lower the tracks into a tunnel concealed by walls and landscaping. The Hill-Tunnel plan, supported by Saarinen and NPS engineer Julian Spotts, favored a tunnel below Second and First Streets to contain the tracks. On July 7, 1949, in Mayor Joseph Darst

 declared that the Department of the Interior and the railroads should come to an agreement on the relocation before authorization could be rehashed. In October, NPS and the TRRA decided that the TRRA would employ a surveyor endorsed by Spotts to "to survey, design, estimate, and report on" the expenses of the relocation. They chose Alfred Benesch and Associates, which released its last report on May 3, 1957, estimating the cost of two relocation plans at high values—over $11 million and over $14 million, respectively. NPS director Conrad Wirth enjoined Saarinen to make small modifications to the design. In October, Saarinen redrafted the relocation plans, suggesting:

s did not include funding national memorials. In 1956, Congress appropriated $2.64 million to be used to relocate the railroad. The remainder of the authorized appropriation was requested via six congressional bills, introduced on July 1, 1958, that revised Public Law 361 to encompass the cost of the entire memorial, increasing federal funds by $12.25 million. A month later the Department of the Interior and the Bureau of the Budget endorsed the bill, and both houses of Congress unanimously passed the bill. Eisenhower signed it into law on September 7. The NPS held off on appropriating the additional funds, as it planned to use the already appropriated funds to initiate the railroad relocation.

 buildings near the arch. In April 1959, real estate developer Lewis Kitchen decided to construct two 40-level edifices across from the arch. In July, after the plan was condemned for its potential obstruction of the arch, Kitchen discussed the issue with officials. A decision was delayed for several months because Saarinen had yet to designate the arch's height, projected between 590 and 630 ft (179.8 and 192 m). By October, Mayor Tucker and Director Wirth resolved to restrict the height of buildings opposite the arch to 275 feet (83.8 m) (about 27 levels), and the city stated that plans for buildings opposite the arch would require its endorsement. Kitchen then decreased the height of his buildings, while Saarinen increased that of the arch.

Railroad relocation was the first stage of the project. On May 6, 1959, after an official conference, the Public Service Commission called for ventilation to accompany the tunnel's construction, which entailed "placing 3,000 feet of dual tracks into a tunnel 105 feet west of the elevated railroad, along with filling, grading, and trestle work." On June 8 in the Old Courthouse, eight bids for the relocation program were reviewed. The MacDonald Construction Company bid the lowest amount—$2,426,115, less than NPS' estimate of the cost—and garnered the contract. At 10:30 a.m. on June 23, 1959, the groundbreaking

 ceremony occurred with Tucker's spading the first portion of earth. Wirth and Dickmann also delivered speeches.

The NPS acquired the $500,000 in escrow and transferred it to MacDonald to initiate railroad relocation. In August, demolition of the Old Rock House was complete, with workers beginning to excavate the tunnel. In November, they began shaping the tunnel's walls with concrete. Twenty-nine percent of the construction was completed by March and 95% by November. On November 17, trains began to use the new tracks. June 1962 was the projected date of fruition.

On May 16, 1959, the Senate appropriations subcommittee received from St. Louis legislators a request for $2.4911 million, of which it granted only $133,000. Wirth recommended that they reseek the funds in January 1960.

On March 10, 1959, Regional Director Howard Baker received $888,000 as the city's first subsidy for the project. On December 1, 1961, $23,003,150 in total had been authorized, with $19,657,483 already appropriated—$3,345,667 remained not yet appropriated.

Construction

The bidding date, originally December 20, 1961, was postponed to January 22, 1962, to clarify the details of the arch construction. About 50 companies that had requested the construction requirements received bidding invitations. Extending from $11,923,163 to $12,765,078, all four bids exceeded the engineer estimate of $8,067,000. Wirth had a committee led by George Hartzog

 determine the validity of the bids in light of the government's conditions. Following a meeting with the bidders, the committee affirmed the bids' reasonableness, and Wirth awarded the lowest bidder, MacDonald Construction Company, the contract for the construction of the arch and the visitor center. On March 14, 1962, he signed the contract and received from Tucker $2,500,000, the city's subsidy for the phase. MacDonald reduced its bid $500,000 to $11,442,418. The Pittsburgh-Des Moines Steel Company served as the subcontractor for the shell of the arch.

Contractor MacDonald Construction Co. arranged a 30 feet (9.1 m) tower for spectators and provided recorded accounts of the undertaking. In 1963, a million people went to observe the progress, and by 1964, local radio stations began to broadcast when large slabs of steel were to be raised into place.

The project manager of MacDonald Construction Co., Stan Wolf, said that a 62-story building was easier to build than the arch: "In a building, everything is straight up, one thing on top of another. In this arch, everything is curved."

 firm predicted thirteen workers would die while building the arch, no worker was killed during the monument's construction. However, construction of the arch was still often delayed by safety checks, funding uncertainties, and legal disputes.

Civil rights activists regarded the construction of the arch as a token of racial discrimination. While African Americans worked on the arch, none were skilled laborers. On July 14, 1964, during the workers' lunchtime, civil rights protesters Percy Green and Richard Daly, both members of Congress of Racial Equality

, climbed up 125-feet on the north leg of the arch to "expose the fact that federal funds were being used to build a national monument that was racially discriminating against black contractors and skilled black workers." As the pair disregarded demands to get off, protesters on the ground demanded that at least 10% of the skilled jobs belong to African Americans. Four hours later Green and Daly dismounted from the arch, to charges of "trespassing, peace disturbance, and resisting arrest."

In 1964, the Pittsburgh-Des Moines Steel Company sued MacDonald for $665,317 for tax concerns. In 1965, NPS requested that Pittsburgh-Des Moines Steel remove the prominent letters "P-D-M" (its initials) from a creeper derrick used for construction, contending that it was promotional and violated federal law with regards to advertising on national monuments. Although Pittsburgh-Des Moines Steel initially refused to pursue what it considered a precarious venture, the company relented after discovering that leaving the initials would cost $225,000 and after that, $42,000 per month, and the NPS dropped its lawsuit.

On October 26, 1965, the International Association of Ironworkers delayed work to ascertain that the arch was safe. After NPS director Kenneth Chapman gave his word that conditions were "perfectly safe," construction resumed on October 27. After the discovery of 16 defects, the tram was also delayed from running.

The ceremony date was reset to October 17, 1965, and workers strained to meet the deadline, taking double shifts, but by October 17, the arch was still not complete. The chairman of the ceremony anticipated the ceremony to be held on October 30, a Saturday, to allow 1,500 schoolchildren, whose signatures were to be placed in a time capsule, to attend.

 had constricted the 8.5-foot gap at the top by 5 inches (12.7 cm). To mitigate this, workers used fire hoses to spray water on the surface of the south leg to cool it down and make it contract. The keystone was inserted in 13 minutes, only 6 inches (15.2 cm) remained. For the next section, a hydraulic jack had to pry apart the legs six feet. The last section was left only 2.5 foot (0.762 m). By 12:00 p.m., the keystone was secured. Some filmmakers, in hope that the two legs would not meet, had chronicled every phase of construction.

The Gateway Arch was expected to open to the public by 1964, but in 1967 the public relations agency stopped forecasting the opening date. The arch's visitor center opened on June 10, 1967 and the tram began operating on July 24.

The arch was dedicated by Humphrey on May 25, 1968. He declared that the arch was "a soaring curve in the sky that links the rich heritage of yesterday with the richer future of tomorrow" and brings a "new purpose" and a "new sense of urgency to wipe out every slum." "Whatever is shoddy, whatever is ugly, whatever is waste, whatever is false, will be measured and condemned" in comparison to the Gateway Arch. About 250,000 people were expected to attend, but rain canceled the outdoor activities. The ceremony had to be transferred into an auditorium, which later became a museum.

After the dedication, Humphrey crouched beneath an exit as he waited for the rain to subside so he could walk to his vehicle. Reporters quipped with him and solicited autographs as the rain surged over a clogged seepage grill. Seeing this, Humphrey smiled, "This is ridiculous."

Economic impact

The project did not provide 5,000 jobs as expected—as of June 1964, workers numbered fewer than 100. The project did, however, incite other riverfront restoration efforts, totaling $150 million. Building projects included a 55,000-seat sports stadium, a 400-unit motel, a 24-story hotel, four parking garages, and an apartment complex. The idea of a Disneyland amusement park that included "synthetic riverboat attractions" was considered but later deserted. The developers hoped to use the arch as a commercial catalyst, attracting visitors who would use their services.

Physical characteristics

Both the width and height of the arch are 630 feet (192 m). The arch is the tallest memorial in the United States and the tallest stainless steel monument in the world.

The cross-sections of the arch's legs are equilateral triangles, narrowing from 54 feet (16.5 m) per side at the bases to 17 feet (5.2 m) per side at the top. Each wall consists of a stainless steel

. The arch is resistant to earthquakes and is designed to sway up to 9 inches (22.9 cm) in either direction while withstanding winds up to 150 miles per hour (241.4 km/h). The structure weighs 42878 short tons (38,898.3 MT), of which concrete comprises 25980 ST (23,568.7 MT); structural steel interior, 2157 ST (1,956.8 MT); and the stainless steel panels that cover the exterior of the arch, 886 ST (803.8 MT). This amount of stainless steel is the most used in any one project in history. The base of each leg at ground level had to have an engineering tolerance of 1/64 in or the two legs would not meet at the top.

. A chain that supports only its own weight forms a catenary; in this configuration, the chain is strictly in tension. An inverted catenary arch that supports only its own weight is strictly in compression, with no shear. The catenary arch is the stablest of all other arches since "the thrust passes down through the legs and is absorbed in the foundations, whereas in other arches, the pressure tends to force the legs apart." The Gateway Arch itself is not a common catenary, but a more general curve of the form y=Acosh(Bx). This makes it an inverted weighted catenary—the arch is thicker at its two bases than at its vertex. Saarinen chose a weighted catenary over a normal catenary curve because it looked less pointed and less steep. In 1959, he caused some confusion about the actual shape of the arch when he wrote, "This arch is not a true parabola

On December 8, 2009, sponsored by nonprofit CityArchRiver2015, the international design competition "Framing a Modern Masterpiece: The City + The Arch + The River 2015" commenced. It aimed to "design a plan to improve the riverfront park landscape, ease access for pedestrians across Memorial Drive and expand onto the East St. Louis riverfront," as well as to lure visitors. The contest consisted of three stages—portfolio assessment (narrowed down to 8–10 teams), team interviews (narrowed down to 4–5 teams), and review of design proposals. The competition received 49 applicants, which were narrowed down to five in the first two stages. On August 17, 2010, the designs of the five finalists were revealed to the public and exhibited at the theater below the arch.

Visitor center

The underground visitor center for the arch was designed as part of the National Park Service's Mission 66

 program. The 70000 ft2 center is located directly below the arch, between its legs. Although construction on the visitor center began at the same time as construction for the arch itself, it did not conclude until 1976 because of insufficient funding; however, the center opened with several exhibits on June 10, 1967. Access to the visitor center is provided through ramps adjacent to each leg of the arch.

The center houses offices, mechanical room

s, and waiting areas for the arch trams, as well as its main attractions: the Museum of Westward Expansion and two theaters displaying films about the arch. The older theater opened in May 1972; the newer theater, called the Odyssey Theatre, was constructed in the 1990s and features a four-story-tall screen. Its construction required the expansion of the underground complex, and workers had to excavate solid rock while keeping the disruption to a minimum so the museum could remain open. The museum houses several hundred exhibits about the United States' westward expansion in the 19th century and opened on August 10, 1977.

Observation area

Near the top of the arch, passengers exit the tram compartment and climb a slight grade to enter the arched observation area. There are 32 windows (16 per side), each measuring 7 by 27 in (177.8 by 685.8 mm) and allowing views across the Mississippi River

 to the west beyond the city. The observation deck, 65 feet (19.8 m) long and 7 feet (2.1 m) wide, has a capacity of about 160 passengers—the capacity of four trams. On a clear day, one can see up to 30 miles (48.3 km) from atop the arch.

Modes of ascension

There are three modes of transportation up the arch: two sets of 1,076-step emergency stairs (one in each leg), a 12-passenger elevator to the 372 feet (113.4 m) height, and a tram in each leg.

Because of a lack of funds in March 1962, the NPS did not accept bids for the arch's internal train system and considered discarding the idea. In May 1962, the quasi-governmental Bi-State Development Agency

 proposed that it issue revenue bonds to obtain the required funds. The Department of the Interior and Bi-State entered into an agreement where Bi-State would construct and operate the tram. Bi-State would have to raise $1,977,750 for the construction of the tram system. It retired the bonds by setting a $1 riding fee to the top. Two months later, the agency had already received 45 advance reservations for seats on the tram.

s and has operated the tram system since. The tram in the north leg entered operation in June 1967, but visitors were forced to endure three-hour long waits until April 21, 1976, when a reservation system was put in place. As of 2007, the trams have traveled 250000 miles (402,335 km), conveying more than 25 million passengers.

Each tram is a chain of eight egg-shaped, five-seat compartments with a small window on the doors. As each tram has a capacity of 40 passengers and there are two trams, 80 passengers can be transported at one time, with trams departing from the ground every 10 minutes. The cars swing like Ferris-wheel

 cars as they ascend and descend the arch. This fashion of movement gave rise to the idea of the tram as "half-Ferris wheel and half-elevator." The trip to the top takes four minutes, and the trip down takes three minutes. At the top, passengers disembark to a 65 feet (19.8 m)-long observation area.

Incidents

On July 8, 1970, a six-year-old boy, his mother, and two of her friends were trapped in a tram in the arch's south leg after the monument closed. According to the boy's mother, the group went up the arch around 9:30 p.m. CST, but when the tram reached the de-boarding area, its doors did not open. The tram then reportedly traveled up to a storage area 50 feet (15.2 m) above the ground, and the power was switched off. One person was able to pry open the tram door and the four managed to reach a security guard for help after being trapped for about 45 minutes.

On July 21, 2007, a broken cable forced the south tram to be shut down, leaving only the north tram in service until repairs were completed in March 2008. Around 200 tourists were stuck inside the arch for up to three hours because the severed cable contacted a high-voltage rail, causing a fuse to blow. The north tram was temporarily affected by the power outage as well, but some passengers were able to exit the arch through the emergency stairs and elevator. It was about two hours until all the tram riders safely descended, while those in the observation area at the time of the outage had to wait an additional hour before being able to travel back down. An arch official said the visitors, most of whom stayed calm during the ordeal, were not in any danger; they were later given refunds. The incident occurred while visitors in the arch were watching a fireworks display, and no one was seriously injured in the event. However, two people received medical treatment; one person needed oxygen

 and the other was diabetic. Almost immediately after the tram returned to service, however, it was closed again for new repairs after an electrical switch broke. The incident, which occurred on March 14, 2008, was billed as a "bad coincidence."

On the morning of February 9, 2011, a National Park Service worker was injured while performing repairs on the south tram. The 55-year-old was working on the tram's electrical system when he was trapped between it and the arch wall for around 30 seconds, until being saved by other workers. Emergency officials treated the injured NPS employee at the arch's top before taking him to Saint Louis University Hospital

On March 24, 2011, around one hundred visitors were stranded in the observation area for 45 minutes after the doors of the south tram refused to close. The tourists were safely brought down the arch in the north tram, which had been closed that week so officials could upgrade it with a new electronic transportation system. The National Park Service later attributed the malfunction to a computer glitch associated with the new system, which had already been implemented with the south tram. No one was hurt in the occurrence, but the arch suffered a slight loss in spring break

Around 2:15 p.m. local time on June 16, 2011, the arch's north tram stalled due to a power outage. The tram became stuck about 200 feet (61 m) from the observation deck, and passengers eventually were told to climb the stairs to the observation area. It took National Park Service workers about one hour to manually pull the tram to the top, and the 40 trapped passengers were able to return down on the south tram, which had previously not been operating that day because there was not an abundance of visitors. An additional 120 people were at the observation deck at the time of the outage and also exited via the south tram. During the outage, visitors were stuck in the tram with neither lighting nor air conditioning. No one was seriously injured in the incident, but one visitor lost consciousness after suffering a panic attack

, parachuted on to the top of the arch. (His plan was to release his main parachute and then jump off the arch using his reserve parachute, a "BASE" jump). Unfortunately, after landing the wind blew him to the side, and he slid down the north leg to his death. The accident was witnessed by several people, including Swyers' wife, also a parachutist. She said her husband "was not a hot dog, daredevil skydiver" and that he had prepared for the jump two weeks in advance. Swyers, who had made over 1,600 jumps before the incident, was reported by one witness to have "landed very well" on the top of the arch, but "had no footing." Swyers was reportedly blown to the top of the arch by the wind and was unable to save himself when his reserve parachute failed to deploy. The Federal Aviation Administration said the jump was unauthorized, and investigated the pilot involved in the incident.

 costume when he jumped off an airplane around 8:00 a.m. CST, parachuted onto the arch, grasped the monument's beacon, and used the same chute to glide down unharmed. KTVI said it was told the feat was done as an act of homage to Swyers, and "apparently was a combination of a dare, a drunk and a tribute." On the day after the alleged incident, authorities labeled the jump a hoax. A spokesperson for the St. Louis Metropolitan Police Department said no calls were received about the jump until after it was detailed on the news, and the Federal Aviation Administration said the two calls it had received were very similar. One caller also left an out-of-service phone number, while the other never followed up with investigators. Arch officials said they did not witness any such jump, and photos provided by the alleged parachutist were unclear.

In an interview, Vincent said he visited the arch's observation area a month before the stunt, to see if he could use a maintenance hatch for accessing monument's peak. Due to the heavy security, he instead decided to climb up the arch's exterior using suction cups, which he had used before to scale shorter buildings. Dressed in black, Vincent began crawling up the arch around 3:30 a.m. CST on September 14 and arrived undetected at the top around 5:45 a.m., taking an additional 75 minutes to rest and take photos before finally jumping. During this time, he was seen by two traffic reporters inside the One Metropolitan Square

Vincent was also spotted mid-air by Deryl Stone, a Chief Ranger for the National Park Service. Stone reported seeing Vincent grab his parachute after landing and run to a nearby car, which quickly drove away. However, authorities were able to detain two men on the ground who had been videotaping the jump. Stone said 37-year-old Ronald Carroll and 27-year-old Robert Weinzetl, both St. Louis residents, were found with a wireless communication headset and a video camera, as well as a still camera with a telephoto lens

In his decision, Noce stated, "There are places in our country where the sufficiently skilled can savor the exhilaration and personal satisfaction of accomplishing courageous and intrepid acts, of reaching dreamed-of heights and for coursing dangerous adventures," but added that other places are designed for "the exhilaration of mere observation and for the appreciation of the imaginings and the works of others. The St. Louis Arch and the grounds of the Jefferson National Expansion Memorial are in the latter category."

Symbolism and culture

Built as a monument to the westward expansion of the United States, the arch typifies "the pioneer spirit of the men and women who won the West, and those of a latter day to strive on other frontiers." The arch has become the iconic image of St. Louis, appearing in many parts of city culture. In 1968, three years after the monument's opening, the St. Louis phone directory contained 65 corporations with "Gateway" in their title and 17 with "Arch." Arches also appeared over gas stations and drive-in restaurants.

The arch has also appeared as a symbol of Missouri state. On November 22, 2002, at the Missouri State Capitol

Iain Twiddy of Oxford Journals wrote that the arch "echoes the 'iced-over canal' of the poem's opening, or the birth canal" and that the mirror-image rhyme scheme of the poem, abab cdcd efgf fgfe dcdc baba, is an allusion to the Gateway Arch or the "cervical opening of the poem, as a monument to the dead."

Yes, it is true that he was from St. Louis, which started calling itself the Gateway to the West after Eero Saarinen's Gateway Arch was erected, and I'm from Kansas City, where people think of St. Louis not as the Gateway to the West but as the Exit from the East."
