Illinois department of transportation Starts Critical $164M I-80 Bridge Project

The Illinois Department of Transportation began a $164 million I-80 bridge replacement project over the Des Plaines River. The Silicon Review reports on the critical infrastructure upgrade.

The Illinois Department of Transportation has broken ground on a $164 million project to replace the I-80 bridge over the Des Plaines River near Joliet. The critical infrastructure upgrade will improve safety and reduce traffic congestion on one of the state's busiest freight corridors.

The Illinois Department of Transportation project will replace the existing 1960s-era bridges with modern structures featuring wider lanes, improved shoulders, and better drainage systems. The current bridges carry approximately 80,000 vehicles daily, including 20 percent heavy trucks serving regional distribution centers.

The Illinois Department of Transportation secured federal grants covering 80 percent of the project cost through the Bipartisan Infrastructure Law. The remaining 20 percent comes from state motor fuel taxes. Construction is expected to be completed by late 2029.

The I-80 bridge replacement is part of a broader $1.5 billion modernization of the I-80 corridor through Will County, one of the nation's fastest-growing logistics hubs. The corridor connects the Port of Joliet to the interstate system and serves as a critical link between Chicago and the Quad Cities.

The Illinois Department of Transportation will maintain at least two lanes of traffic in each direction during construction using temporary bridges. The project includes new noise barriers, improved lighting, and enhanced pedestrian and bicycle crossings.
