I-294 BNSF Railway Bridge Project
Central Tri-State Tollway (I-294)
Burlington Northern Santa Fe (BNSF) Railway Bridge Project
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.
On I-294, lane closures and traffic shifts will be necessary to provide a work zone and safely accommodate construction.
Whenever possible, the Tollway uses traffic shifts and shoulders to keep as many lanes open during peak hours as were available before construction.
Prior to rebuilding the current bridge, the Tollway will build a bypass bridge carrying three tracks over I-294 in order to maintain continual freight and commuter rail operations. Once the bypass bridge is complete, the main bridge will be rebuilt.
A Regional Solution
The Central Tri-State Tollway is being reconstructed to increase capacity, reduce congestion and improve travel reliability. This work is part of the Tollway’s 15-year, $14 billion capital program, Move Illinois: The Illinois Tollway Driving the Future. More than 220,000 vehicles use this portion of the Tri-State Tollway daily.
A detailed planning and refinement process is underway to complete a design concept for rebuilding the Central Tri-State Tollway (I-294). This process includes outreach efforts with customers, communities, businesses and partners to identify regional improvements and continue to refine the design details.
Reconstruction of the BNSF Railway Bridge will allow for increased traffic capacity on I-294 and improve the overall driving experience through one of the busiest section of the Tollway.
As the bridge is expected to last for decades to come, the bridge is being designed to accommodate foreseeable future needs to the greatest extent possible.
Work Zone Safety
The Illinois Tollway is committed to ensuring that the Central Tri-State Tollway (I-294) and the railroad remain safe for both drivers and workers during construction, which is part of the agency’s overall commitment to roadway safety.
Work zone speed limits are in effect in all construction zones 24/7 and drivers should continue to watch for changing traffic patterns and use caution, especially when workers are present. On I-294, a 45 mph work zone speed limit is in effect throughout the construction season.
