Elmhurst Road Interchange Project at I-90
The Illinois Tollway has begun construction of a new bridge to carry southbound Elmhurst Road traffic over the Jane Addams Memorial Tollway (I-90). This is the first step in completing an existing partial interchange that currently only provides access to and from the east. This work is part of the Elgin O'Hare Western Access Project and is scheduled to be completed in 2016.
Construction Update (11-18-2013)
Traffic is shifted to the outside shoulders in both directions on I-90 between Elmhurst Road and Higgins Creek to provide a work zone in the median so workers can build bridge piers over the winter in preparation for the placement of bridge beams in early spring. Traffic on Elmhurst Road will not be impacted by this phase of work.
A new, diverging diamond interchange will be constructed at I-90 and Elmhurst Road. Diverging diamond interchanges are designed to eliminate left turns in front of oncoming traffic, smooth traffic flow and reduce congestion. Right turns work the same as they do at conventional interchanges, and traffic is controlled by signals.
In 2013, improvements at Elmhurst Road will include advance work required for construction of a new bridge that will carry southbound Elmhurst Road traffic over I-90.
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 existing ramp movements will remain open during construction.
In 2013, the Elmhurst Road Bridge Project will require traffic shifts and reduced speed limits on I-90 for work to build the new bridge structure. Elmhurst Road traffic will remain on the existing bridge until the new bridge is complete in mid-2014, and then traffic will be shifted onto the new bridge, allowing for the reconstruction and widening of the existing bridge for northbound traffic.
New bridges and ramps will be constructed at the interchange to provide full access between I-90 and Elmhurst Road. The current interchange at Elmhurst Road and I-90 is a partial interchange providing westbound exit and eastbound entrance movements only. These ramps were constructed in 1958 with the original construction of I-90.
The project is estimated at $85 million. These improvements are part of the $3.4 billion Elgin O'Hare Western Access Project, which is included in the Tollway's 15-year, $12 billion capital program, Move Illinois: The Illinois Tollway Driving the Future.
The Tollway is committed to "Building Green" and minimizing the environmental impact of construction by reducing, recycling and reusing materials. New asphalt pavement used for the ramp shoulders may incorporate recycled materials and sustainable practices including warm-mix asphalt, reclaimed asphalt pavement and recycled asphalt shingles. In addition to reducing the cost of this work, reusing materials reduces the need for virgin asphalt materials and reduces the volume of material that would otherwise be sent to landfills.
Work Zone Safety
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. Visit the Tollway's Work Zone Safety page.
