U.S. Route 54 (US 54) in Illinois is a 23.9-mile-long (38.5 km) east–west highway that travels from theChamp Clark Bridge on theMissouri state line to I-72/US 36/IL 107 south of Griggsville. At its greatest extent, US 54 used to continue east toSpringfield, then northeast toOnarga, and then north all the way toDowntown Chicago.
Beginning at the Champ Clark Bridge above theMississippi River, US 54 travels in a northeastern direction. It then intersects IL 96 in Atlas and then travels in a northern direction. Along the way, US 54 comes acrossLyman Scott House inSummer Hill. In New Hartford, the route then travels in a northeastern direction again. After that, it begins to run concurrently with IL 106 all the way toward Pittsfield. In Pittsfield, one block east ofPike County Courthouse, US 54 splits northward. After leaving Pittsfield, the route comes across I-72/US 36/IL 107. At this point, US 54 terminates at thisdiamond interchange.[1]
Initially, US 54 ended at the junction of present-day IL 106 (former portion of US 36).[2] In 1935, it replaced a portion of IL 107 betweenLouisiana, Missouri and New Hartford, Illinois.[3] From 1942 to 1971, US 54 traveled all the way to Downtown Chicago.[4][5] Before it was truncated back to its previous eastern terminus, it followed portions of current-day US 36,IL 54,US 45, IL 50, Governors Highway, Wood Street, 127th Street, Halsted Street, Vincennes Avenue, State Street, and Michigan Avenue.[5][6] The four-lane section of US 36 northeast of Pittsfield now also carries Interstate 72 east to Springfield. As of 1992, US 54 was extended northeast to US 36 and present-day I-72 (exit 35). That same year, the section of road that once carried Illinois Route 54 through Springfield is no longer designated as a numbered highway.[7] Now Illinois Route 54 starts at the Interstate 55 exit and goes northeast to Onarga, where it ends at U.S. Route 45. US 54 once joined with US 45 to Kankakee, but that highway is now designated as US 45 alone to Gilman, then US 45 and US 24 through Gilman, then US 45 alone again until a four-way intersection with U.S. Route 52 and Illinois Route 49, and US 45 and US 52 through Kankakee. Between Kankakee and Monee, the section that once carried US 54 is now marked asIllinois Route 50.
The entire route is inPike County.
