The I-57/I-74 interchange, located just west of Champaign, was built in 1965 and has experienced operational issues due to deficient geometric features. Farnsworth Group is providing Phase III construction engineering services for the project, which will completely reconfigure and replace the traditional cloverleaf interchange with the construction of 11 new structures, including five box culverts, four bridges, and two flyover structures in the middle of the interchange and new ramp pavements. These changes will improve traffic flow, efficiency, and safety by eliminating conflict points and reducing turning movements. A third, auxiliary lane also will be added to both directions of I-74. Some green spaces will be restored with native grass to cut down on future planting.
The multi-year rehabilitation, made possible by the Rebuild Illinois capital program, is a combination of four related projects anticipated to be\ completed in 2025. The culmination of these projects rebuilds a critical regional freight juncture that handles almost 40,000 vehicles per day.
