Interstate 90 is the longest interstate highway in the United States at nearly 3,100 miles . It is the northernmost east-to-west, coast-to-coast interstate. Its western terminus is in Seattle, Washington at 4th Avenue S. next to Qwest Field, and its eastern terminus is in Boston, Massachusetts at Logan International Airport and Massachusetts Route 1A. It crosses the Continental Divide just east of Butte, Montana. Route description In the state of Illinois, Interstate 90 enters from Wisconsin with Interstate 39. At the U.S. Route 51 exit, I-39/90 becomes the Northwest Tollway. The two Interstates run south to Rockford, where I-39 continues south to La Salle/ Peru. I-90 continues southeast along the tollway to the Chicagoland area. In Schaumburg, I-90 meets the western end of Interstate 290, the only loop from I-90 in Illinois. I-90 passes O'Hare International Airport, where Interstate 190, the only spur of I-90 in Illinois, branches west to the airport terminals. I-90 continues southeast as the Kennedy Expressway and joins with Interstate 94 - northbound, I-94 is the Edens Expressway at this point. I-90/94 then pass through the city, intersecting the eastern end of I-290 just west of the Chicago Loop. South of I-290, the highway is given the name of the Dan Ryan Expressway. In Chicago's South Side, I-90 splits off from I-94 and becomes the Chicago Skyway, again becoming a toll road. I-90 then runs directly southeast to the Indiana state line, and becomes the Indiana Toll Road at the state line. In the state of Indiana, Interstate 90 enters from Illinois at the Chicago Skyway. It then runs to the multiplexed Interstates 80/ 94 east of Interstate 65, where I-80 leaves I-94 and joins with I-90. The combined I-80/90 route runs east across northern Indiana and near the southern border of Michigan to the Ohio state line. As part of the Toll Road, I-80/90 passes to the north of South Bend and Elkhart. It also passes north of Angola at Interstate 69.

It is arguable that Interstate 280 is as much a spur of Interstate 90 as it is of Interstate 80 because Interstate 80 and 90 designate the same highway in northwestern Ohio. It links to Toledo, Ohio and, with Interstate 75 to Detroit, Michigan. Interstate 115 in Butte, Montana could make the same claim as well. In fact, the spur is cosigned with Interstate 15 Business and Interstate 90 Business for its entire length. Notes... . - Between LaPorte, Indiana and Toledo, Ohio, with Interstate 80, it is nowhere more than 10 miles from the Michigan state line, though it never enters the state.
- To add to the quirks about the longest interstate, it also has the longest distance twinned with another interstate in the most states . It also intersects the same interstate six times . Additionally, it is part of the longest interstate triplex in the country, as it is joined with I-39 and I-94 from Portage, Wisconsin to Madison, Wisconsin.
Idaho - The small town of Wallace, Idaho still prides itself on having the last stop light on I-90. Its downtown has many historical buildings, which would have been wiped out by the original planned route of the freeway, so in 1976, city leaders had the downtown placed on the National Register of Historic Places. As a result, the federal government was forced at great expense to reroute the freeway to the northern edge of downtown and elevate it. That section of I-90 opened in September 1991. A bicycle path is routed beneath part of that segment.
Illinois - There is some dispute as to whether the Chicago Skyway is an official part of the Interstate highway system. The city of Chicago replaced many I-90 shields to "TO I-90" when it determined that the city may have never applied for Interstate designation for the skyway. However, the Federal Highway Administration considers the Skyway as being part of I-90, and the Illinois DOT has always and continues to report it as such. See List of gaps in Interstate Highways for more information.
Massachusetts - Turnpike Doubles are permitted to travel between exit 11 and through the New York state border.
Montana Montana is a state [i] in the Pacific Northwest [i] and Great Plains [i] regions of the United States [i]... near the Idaho border, I-90 was not a divided highway for a few stretches, having only a narrow paved median. From 1995 until 1999, the speed limit in Montana was "reasonable and prudent"; it is now 75 mph . New York - Almost all of the New York portion of the road is a toll road, comprising the east-west portion of the New York State Thruway mainline and part of the Berkshire Connector, operated by the New York State Thruway Authority. It was originally constructed as part of the Thruway project in the middle 1950s and received its current designation as Interstate 90 in 1958. "I-90" carries Interstate 90 between the two; however, the Berkshire Section directly connects to the mainline 6.5 miles west of the point where I-90 joins it .
- The mileposts and exit numbers on the New York State Thruway mainline originate at the New York City line and increase northward along Interstate 87 and westward along Interstate 90. As a result, mileposts and exit numbers on the I-90 section of the Thruway mainline increase from east to west, contrary to modern practices where numbers increase from the west or south. The NYSDOT-maintained portion in between, known to locals as "Freebie 90," does number its mileage and exits in the traditional west-to-east method. It starts over again when the Berkshire Section of the Thruway begins, with exit and mile numbers preceded by the letter B .
- There used to be two metric-only signs on the westbound New York State Thruway. They were around Syracuse, which is about 100 miles from Canada. The NYS Thruway Authority decided to test metric signage, which may have included an 88 km/h speed limit sign, on the Thruway. There was also a sign displaying the distance to the Interstate 81 interchange in kilometers in Dewitt. These signs are now displayed in just miles.
- I-90 is the only Interstate having a complete set of nine spur routes within one state, which is in New York. In addition, I-990, a short spur route near Buffalo, New York not directly connected to I-90, is the highest number given to an Interstate.
- I-790 in Utica used to have a completely direct connection with the I-90 at Thruway interchange 31. Various road redesign projects over the years have eventually lead to this direct connection being partially severed. Traffic exiting the Thruway must use two different surface streets to reach I-790. However, it is still possible to travel from I-790 directly onto the Thruway. I-790 has some other oddities: no exit numbers, no reassurance shields, and it runs concurrent with New York State Route 5 for its entire length.
Ohio ... , Interstate 90 serves as the Innerbelt at the confluence of the northern termini of Interstates 71 and 77. One of the most peculiar and hazardous stretches of Interstate 90 is the section of highway passing through downtown, known locally as Dead Man's Curve. Here, the road takes a nearly 90-degree turn . While there are plenty of large signs and flashing lights alerting motorists to this turn, there have still been a large number of accidents due to inattentive motorists. There are plans to realign the freeway along a shallower curve within the next decade, as part of a larger project to improve the highway system in Cleveland. Pennsylvania Washington - In 2003, the Seattle terminus was re-engineered to better accommodate traffic from the two nearby sports stadiums. I-90 westbound still ends at its previous location next to Qwest Field, but eastbound begins about 1/4 mile south at Edgar Martinez Dr. near the roof shed of Safeco Field at an interchange with 4th Avenue S.
