Updates on the Tri-State

The Central Tri-State is being reconstructed from Balmoral Avenue to 95th Street to provide congestion relief, reconstruct old infrastructure to meet current and future transportation demand and address regional needs.

Please click here to view the Central Tri-State Tollway (I-294) reconstruction project, concept plan and proposed project timeline.
The Illinois Tollway is reconstructing the Burlington Northern Santa Fe (BNSF) Railway Bridge, which carries the triple-track railroad over the Tri-State Tollway (I-294) between Hinsdale and Western Springs, to accommodate the widening of the Central Tri-State Tollway (I-294).  In 2019, the Tollway will begin work to construct a bypass bridge that will allow for uninterrupted freight and commuter rail operations during bridge reconstruction.  Once the bypass bridge is complete, the main bridge will be rebuilt and lengthened. Work on the BNSF Railway Bridge is scheduled to continue through 2022.

Pedestrian Bridge Updates

Visit the Tollway's Pedestrian Bridge Project webpage.

In coordination with the Village of Hinsdale, the Village of Western Springs and the Western Springs Park District, the Illinois Tollway is building a new pedestrian bridge over the Central Tri-State Tollway (I-294), to maintain a convenient connection between Hinsdale and Western Springs for pedestrians and bicyclists.
The pedestrian bridge is being relocated from its current location near Ogden Avenue to a new site adjacent to 47th Street selected by the Villages of Hinsdale and Western Springs.
The new bridge will be built prior to the old bridge’s removal to allow for full pedestrian access throughout construction.
TheI-294 Pedestrian Bridge Project is part of the Central Tri-State Tollway Project with work scheduled for 2021 to 2023.

The new bridge will meet pedestrian ADA accessibility standards.
