Tri-State Tollway (I-294)

I-294/I-57 Interchange Project - Phase 2

Project Overview

The Illinois Tollway, in partnership with the Illinois Department of Transportation, will begin work in 2019 to complete the interchange connecting the Tri-State Tollway (I-294) to I-57. This final stage of work will build ramps providing access to and from Chicago, improving regional mobility that began with the completion of ramps providing access to and from Champaign in 2014.

To complete the I-294/I-57 Interchange, four new ramps will be built connecting southbound I-57 to I-294 and 294 to northbound I-57. As part of this work, the I-57 median will be reconstructed, and the I-57 mainline will be widened. This work includes earth excavation, drainage improvements, erosion and sediment control, retaining wall and bridge construction.

The second phase of the project is scheduled to begin in the spring and to be completed by the end of 2022.

Customer Impacts

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. 

In 2019, traffic shifts will be needed on I-57 to accommodate center median work.

Building Green

The Tollway is committed to “Building Green” and minimizing the environmental impact of construction by reducing, recycling and reusing materials. In addition to reducing the cost of this work, reuse of these materials reduces the need for virgin asphalt materials and reduces energy consumption, greenhouse gases and the volume of material that would otherwise be sent to landfills.

Work Zone Safety

The Illinois Tollway is committed to ensuring that the Tri-State Tollway (I-294) and I-57 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.
