 once commented that "the road could not have been bad if some unconscionable scoundrel had not now and then dropped a plank across it," after a trip on the Kalamazoo and Grand Rapids Plank Road. By the first decade of the 20th century, only 23 of the 202 chartered turnpikes were still in operation; many companies that received a charter never built their specified roadways. The remaining plank roads were turned over to the state or purchased by railway companies in the early part of the century.

 and Acme was not signposted in the field and the designation ended instead at Fife Lake, about 213 miles (343 km) north of the state line. At the same time, the Michigan State Highway Department (MSHD) redesignated the remainder of M-13, between Fife Lake and Petoskey, as M-131. Public Act 131 of 1931 allowed the MSHD to take control over the city streets that carried state highways through cities in the state. Until this point, the City of Grand Rapids arbitrarily moved the route of state highways through the city on a regular basis. The department took control of a series of streets and fixed the routing of US 131 through the city after the passage of the act. The highway was shifted between Three Rivers and Constantine to the west side of the St. Joseph River in 1936. In late 1938 or early 1939, the MSHD extended US 131 northward over the southern section of M-131. After the changes US 131 turned eastward into Fife Lake and north to Kalkaska

 in 1969.

In 1968, the section of expressway near Mancelona was downgraded to a two-lane highway. The original roadway had been left in place when a new parallel carriageway was built in 1956. During the winter months, the original lanes built in the 1920s were closed because the grade of the roadway accumulated additional snow and made it difficult to plow. The MSHD had considered reconstructing the older road to retain the expressway set up, but that would have cost $1.5 million while removing it and permanently reconfiguring the 1956 roadway cost only $170,000.

The 1970s saw the US 131 freeway expand to north of Grand Rapids. The section between the two M-57 junctions near Rockford and in Cedar Springs opened on September 21, 1973, at a dedication ceremony featuring then-Congressman Gerald R. Ford. By the end of the year, the freeway would be open as far north as Howard City

. At the same time, M-46 was realigned to extend south down the freeway to Cedar Springs and west to replace M-57 west of Rockford.

Construction to complete these sections north of Grand Rapids had been delayed in 1967. Before the delays, the MSHD planned to have the gap in the freeway between Grand Rapids and Cadillac completed by 1974. The state even proposed adding the freeway north of Grand Rapids to Petoskey, with a further continuation to Mackinaw City

–Osceola county line was opened on November 9, 1976, at a cost of $7.4 million. By 1977, the state postponed any plans to complete the freeway north of Cadillac. The department cited rising construction material costs and opposition to the freeway in Petoskey. By the end of the decade, I-296 signs were removed from the section of freeway in Grand Rapids. However, the freeway remains listed as a part of the Interstate Highway System.

 were designated as a business loop simultaneously. US 131 followed 19 Mile Road between the end of the freeway and the former routing north of town. The gap was filled in when the freeway segment between Big Rapids and Osceola County was opened in 1986. The section of highway along 19 Mile Road was transferred to the Big Rapids business loop to connect it back to the new freeway. When the expansions ended, in the mid-1980s, it was expected that the US 131 freeway would end at the south side of Cadillac, "perhaps forever". MDOT had ended all consideration of additional freeway mileage in 1981, citing decreased gas tax revenues, decreased traffic and higher construction costs. A 1979 report said that while traffic forecasts showed continued growth, upgrades to existing roads would be sufficient to handle traffic needs.

S-Curve replacement

One of the more unusual sections of the US 131 freeway in the Grand Rapids area is the S-Curve. This section of freeway carries US 131 over the Grand River with two sharp turns in the road, resembling the letter S. The design for this structure was completed in 1952 and placed the freeway on the least expensive land in the area, despite the knowledge that it would someday create issues. As noted by the The Grand Rapids Press in 1981, "the speed limit on the S-Curve must be reduced as low as 25 mph [25 miles per hour (11.2 m/s)] on some bad-weather days because of the sharpness of the turns and [the] numerous accidents [that] have occurred there."

On December 27, 1999, the state awarded a $85.7 million contract for the replacement of the S-Curve on US 131. Deposits of gypsum

 under the roadway were dissolving and causing it to settle. A deteriorating bridge also forced the reconstruction of the freeway through the area. Construction began on January 15, 2000, diverting the roughly 115,000 vehicles per day that used the stretch of road to detours through the downtown area. As part of the project, a $1.2 million de-icing system was installed. The system is designed to spray a de-icing fluid on the roadway that would be carried by car tires up to a mile (1.6 km) along the road surface. This fluid is expected to melt ice at temperatures below the -20 F at which salt stops working. Unlike salt, the non-corrosive de-icer does not harm the bridge, but it is more costly. The system is designed to be activated manually, or automatically via sensors along the road. However, plowing would still be required on the roadway. The idea behind the de-icing system is to keep the pavement wet and prevent the formation of ice.

Construction delays were caused by river flooding during spring rains. A design mistake meant that one of the bridges in the structure was built a foot (1 feet (30.5 cm)) too low, and Grandville Avenue was lowered to compensate for the error. Before the opening, MDOT held a ribbon-cutting ceremony on the freeway to allow local residents to walk along the structure on August 12. The first northbound lanes were opened to traffic in mid-August, three weeks ahead of schedule. Lead contractor Kiewit Western, a company whose "employees have been known to work 13-hour days and 100-hour weeks", accelerated their work schedule over the course of the project to compensate for the delays and still finish the venture early. The remaining lanes opened to traffic on October 26, also ahead of schedule. Additional work started after the main roadway opened by closing various ramps for reconstruction. This work also focused on restoring parking lots located under or adjacent to the freeway and testing the de-icing system; the final ramps were opened in early December 2000 and early January 2001. The end result of the construction produced a freeway design that increased the rated traffic speed from 45 mile per hour.

Recent freeway extensions

MDOT approved a $3.5 billion 10-year transportation plan in 1986 that included an extension of the US 131 freeway north to Manton

 east of downtown. US 131 remained routed through downtown, but M-55 was rerouted to the bypass. Local residents were allowed to use the northern section of the bypass for recreational activities until it was opened to traffic. The full 9.2 miles (14.8 km) bypass around Cadillac was dedicated to Sidney Ouwinga in a ceremony on October 27, 2001, and the road was opened to traffic on October 30, 2001. The former routing through town was redesignated BUS US 131 at the same time. Ouwinga was a state lawmaker who died in 1991 while serving in the Michigan House of Representatives. He was also a member of the US 131 Area Development Association which promoted further northern extensions of the freeway. The 10.5 miles (16.9 km) freeway expansion north around the city of Manton

 was opened in 2003. The former routing was redesignated as a business loop at the time. The two bypasses cost $146 million to complete.

Future

Originally, MDOT and its predecessor agencies had planned to convert US 131 into a freeway all the way to Petoskey. They suggested adding the highway to the Interstate Highway System in the late 1960s, when the federal government took proposals for additions to the network of highways. While further northward extension of the freeway from Manton to Kalkaska and beyond was postponed by the department in the 1970s, and canceled "perhaps forever" in the early 1980s, MDOT made an attempt to revive the extension to Kalkaska in 2000. The proposal was ultimately abandoned when the year's transportation plan was finalized. A bridge replacement project over the Manistee River in 2009–10 ensured the end of further consideration by MDOT of the proposal. According to the local project director, "currently, the department has no plans [to expand the freeway]. Someday it may happen, but not in the foreseeable future."

A southerly extension of the freeway to or near the Indiana state line is still under study. Improvements to the US 131 corridor from Portage to the Indiana Toll Road have been underway for several years and although a late-2005 decision by MDOT to not pursue a new controlled-access route through St. Joseph County

. The new highway would maintain access to local roads via at-grade intersections, and the department would maintain jurisdiction of the old route through town. MDOT has stated that present traffic demands do not warrant the cost of a full freeway facility on a new alignment from the Indiana Toll Road to north of Three Rivers, stating that such a project would cost over $300 million to build. Construction plans were placed on hold after an announcement in June 2009 as various proposals around the state, including the Constantine bypass, were shelved until funding issues could be resolved. In total, 137 road and bridge projects totaling $740 million were delayed to 2012 because the state could not match available federal funding to pay for the work.

Design plans for the new bridge over the St. Joseph River were announced in January 2011. The expected groundbreaking on the venture is scheduled for 2012 with completion in 2014. MDOT currently has $9 million of the projected $25 million to complete the Constantine bypass. Residents in the community are divided over the proposed five-mile (8.0 km) highway. Business owners look to the 3,000 cars and trucks that pass through downtown Constantine each day for customers, traffic that would be diverted around the village by the new roadway. On the other hand, residents that work outside of the small community are looking forward to decreased commute times to their workplaces.

, the poet from the Hoosier State, with a highway that connected the country's summer and winter resort areas. The Michigan segment of the road running through the state was to follow what would later be US 131. The James Whitcomb Riley Association promoted the highway by painting white bands on telephone poles with the name of the road in orange letters during that August and September. However, the road in question was already named the Mackinaw Trail, and the association did not secure permission of the state highway commissioner, as was required by a 1919 Michigan law. The law made it illegal for any "association to delineate or mark any other routes or trails through the State of Michigan... unless the same shall be approved in writing by the State Highway Commissioner." As a result, government officials refused to endorse the association's proposal, and Michigan was excluded from the highway. The efforts of the national association were stunted by the halted progress, and the highway was disbanded by December 1926.

The Michigan Trail, another auto trail from the 1920s, "followed just about every major trunk line at that time in the Lower Peninsula and covered over a thousand miles [1000 miles (1,609.3 km)] of state highways." The Michigan Trail started in Toledo, Ohio

 and a route between Port Huron and Big Rapids. The highway failed as a concept because it lacked focus, and many of the segments of roadway had already assigned names.

The most recent name applied to US 131 is related to the first. Enacted in 2004, Public Act 138 added an additional name to the Mackinaw Trail from the M-66 junction near Kalkaska to Petoskey, the "Green Arrow Route - Mackinaw Trail". Residents of the state have questioned the wisdom of having a "compound road name whose signboards [would] be nearly as long as the highway itself."

Historic bridges

MDOT maintains a listing of historic bridges that includes two which formerly carried US 131. In 1913, the State Trunk Line Act required the highway department to build and maintain bridges at the state's expense if they were included in the nascent highway system. Among the first of these state-built structures is the Division Avenue – Plaster Creek Bridge in Grand Rapids. The crossing is listed on the NHRP for its architectural and engineering significance. Built as Trunk Line Bridge No. 3 over Plaster Creek

 in 1914 by the MSHD, the span cost just over $6,000. Division Avenue carried US 131 until the construction of the freeway through Grand Rapids in the 1960s. The bridge, a filled spandrel arch design, is 50 feet (15.2 m), and was modified in 1935 to widen its deck from 28 feet (8.5 m) to the current 43 feet (13.1 m). The structure was added to the NRHP on December 17, 1999.

The second bridge listed by MDOT is the crossing of the Little Muskegon River for 190th Avenue in southern Mecosta County. Like the Plaster Creek bridge, this structure was also built by the MSHD under the Trunk Line Act of 1913. Built in 1916–17 the 45 feet (13.7 m), 18 feet (5.5 m), concrete through-girder bridge cost around $10,000 to build. It was initially named Trunk Line Bridge No. 61. The span is the oldest concrete girder bridge designed by the MSHD. US 131 followed 190th Avenue over the river until a realignment shifted the highway to another route in 1927.
