Central Tri-State Tollway (I-294)

Plainfield Road Bridge Project

The Illinois Tollway is removing the existing local road bridge carrying Plainfield Road traffic over the Tri-State Tollway (I-294) and rebuilding it with a new, longer and higher bridge structure to accommodate the reconstruction and widening of the Central Tri-State Tollway.

The new bridge will be built to provide for two lanes of traffic, as well as additional pedestrian and bicycle access.

Construction is scheduled to be complete by the end of 2022.

Construction Update (9/10/21)

On Plainfield Road, traffic in both directions is shifted onto the north side of the bridge so work can begin to remove and rebuild the south side. One lane of traffic in both directions will be maintained in the construction work zone on Plainfield Road throughout construction. .

Please check the Daily Construction Alert for up-to-date closure information.

Customer Impacts

Lane closures and traffic shifts on Plainfield Road will be necessary to provide a work zone to safely accommodate traffic and construction.

Electronic message signs and construction signage will be put in place in advance to alert drivers to scheduled lane closures, traffic patterns and work zone speed limits.

During construction, traffic on the Plainfield Road Bridge will be shifted, but one lane in each direction will remain open.
