Interstate 474 encyclopedia topics

Route description

Interstate 474 is a modern, Interstate-standard four-lane freeway for its entire length. Prior to 2006, thru truck traffic on I-74 was instructed to use I-474. This is because prior to its 2004-2007 reconstruction, Interstate 74 was significantly below Interstate standard, having numerous 15 mph onramps and offramps, extremely short merging space for onramps (some less than 500 feet (152 m) in length), and a 45 mph speed limit through downtown Peoria.

The Illinois Route 116 access interchange at Maxewell Road has been indicated as the eastern terminus for the Quincy to Peoria expressway now known as the Illinois Route 336 project.

The western terminus of the interstate is at I-74, exit #87A. The eastern terminus of the route is at I-74, exit #100. North of the western terminus, the route continues as Illinois Route 6 with a new series of exit numbers.

History

I-474 was constructed through the mid 1970s. The now-named Shade-Lohmann Bridge was erected in 1973. During that year, $30.1 million was allocated for acquisition of right-of-way, grading work and overpass/bridge construction across the whole length of the highway.
