U.S. Route 67 (US 67) is a component of the United States Numbered Highway System that connects Presidio, Texas, to Sabula, Iowa.

Since the 1980s, a group called Corridor 67 has taken up the cause of advocating the widening of US 67 to a four-lane highway for the majority of its length.

[2][3] In Carrollton, US 67 meets IL 108 at the northeastern corner of the block on which the Greene County Courthouse sits.

It then continues north and passes through Belltown and White Hall, in the latter of which, IL 106 splits off at a Y intersection and US 67 curves to the northeast.

The second, with Morton Avenue, a former alignment of US 36 and current Interstate business loop, provides access to central Jacksonville.

From there, US 67 heads north past the campus of Western Illinois University and then becomes a four-lane highway before crossing the La Moine River.

After briefly entering downtown Milan, the road turns to the northwest and crosses the Hennepin Canal and two channels of the Rock River separated by Vandruff Island.

Route 3 was planned from Morrison to Chester by way of the Quad Cities, Monmouth, Beardstown, Jacksonville, Alton, and East St.

[9] Residents of Woodson got together with members of the Mississippi Valley Highway association in late 1920 to petition the state to have Route 3 pass through their community rather than one-half mile (800 m) to the west.

Another $100 million bond package (equivalent to $1.41 billion in 2023[7]) was floated to voters that November and passed by a large majority.

[13][14] The American Association of State Highway Officials (AASHO, now AASHTO) communicated to the director of the Illinois Department of Public Works and Buildings in early 1930 that they were going to extend US 67 north from Fredericktown to Davenport by way of Alton and most of Route 3 north of East St. Louis.

Men were standing at the feet of the closed bridges with poles trying to force chunks of ice underneath.

The local highway supervisor noted that the pier rested on bedrock, so simply jacking up the bridge back into position would make it suitable for vehicular traffic.

[25] A $1.5-million project (equivalent to $15.2 million in 2023) to replace the four bridges that connected Rock Island and Milan was completed in November 1949.

[28] Another US 67 Alternate was created in 1952 as a result of the construction of a 32-mile-long (51 km), straighter, and modern highway being built between Medora and Murrayville.

They wanted to reduce through traffic in Jerseyville, Carrollton, and White Hall and the new highway only went through the downtown area of Greenfield.

[32] In downtown Jacksonville, the mayor wanted to reduce the number of heavy trucks, especially those hauling gasoline or liquid propane, driving through the central business district.

Citing improvements to US 67 and US 67 Bypass in the St. Louis area, Illinois highway officials felt the alternate route utilizing the MacArthur Bridge simply was no longer necessary.

[35] The next year, officials sought to remove the other alternate route north of Godfrey because it was causing confusion among motorists.

[39] The mayor also showed frustration in the lack of progress with the state, especially after an Illinois River bridge in Calhoun County was approved.

At the time, the population of Calhoun County was lower than the daily number of vehicles using the Clark Bridge.

[42] A report in 1982 listed four locations, all of which were within 6,500 feet (2,000 m) of the original bridge, for consideration by the Illinois and Missouri departments of transportation.

[50] The Great Flood of 1993 did not damage the bridge and construction was only delayed for two months when the U.S. Army Corps of Engineers closed the river to barge traffic.

[53] Illinois Secretary of State, and later governor, Jim Edgar expressed support for the Corridor 67 group's aspirations and hoped the route would be selected for the Avenue of the Saints highway.

[54] In order to sweeten their proposal to attract the Avenue of the Saints, IDOT officials offered to increase their share of construction costs from 20 to 30 percent.

Both major political party candidates in the 1992 U.S. Senate election for Illinois supported funding the project.

The Democratic Party candidate and eventual winner, Carol Moseley Braun, even received reassurance from Senator Daniel Patrick Moynihan of New York, who at the time was the chair of the senate committee that oversees federal highway funding.

[56] By 1994, Corridor 67 formed a political action committee, PAC 67, with the express intent of bringing attention to their project.

Gubernatorial candidate and eventual winner George Ryan suggested moving fuel taxes back into the transportation budget in order to fund the US 67 project.

[60] The change was made to apply the US 67 designation to the entire Corridor 67 route before major projects began rather than after.
