In 2014, the Illinois Tollway has completed the $5 million Business U.S. Route 20/State Street Interchange Project on the Jane Addams Memorial Tollway (I-90) in Rockford. Work this year included repairs to the pavement connecting the I-90 ramps to Business U.S. Route 20/State Street. Drainage and storm sewer pipe improvements are also part of the project. In 2013, construction was completed to rebuild the four ramps at the Business U.S. Route 20/State Street Interchange.  

Construction Update (12-22-14)

Pavement repair work at the Business U.S. Route 20/State Street Interchange has been completed. Guardrail work at the interchange will continue through the end of the year. 

Project Summary

The pavement and shoulders on all four ramps at this full-access interchange have been removed and replaced with new asphalt ramps. Work in 2014 included drainage and storm sewer pipe work, as well as improvements on the pavement connecting the ramps to Business U.S. Route 20/State Street.

Maintenance of Traffic
Whenever possible, the Tollway uses traffic shifts and shoulders to keep as many lanes open during peak hours as were available before construction. All ramps will remain open during construction by shifting traffic.

Rebuilding the 54-year-old interchange ramps is part of the 15-year, $12 billion capital program, Move Illinois: The Illinois Tollway Driving the Future. The $5 million project will extend the life of the interchange and provide a smooth, new roadway surface for drivers.

Building Green

The Tollway is committed to "Building Green" and minimizing the environmental impact of construction by reducing, recycling and reusing materials. The new asphalt pavement on the ramps will incorporate recycled materials including warm-mix asphalt, reclaimed asphalt pavement and recycled asphalt shingles. In addition to reducing the cost of this work, reuse of these materials reduces the need for virgin asphalt materials and reduces the volume of material that would otherwise be sent to landfills.

Work Zone Safety

A 20 mph work zone speed limit is in place on the ramps connecting I-90 and Business U.S. Route 20/State Street. Construction 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.
