In 2014, work continues to build the new Elmhurst Road Interchange on the Jane Addams Memorial Tollway (I-90).  The Illinois Tollway will complete construction of a new bridge to carry southbound Elmhurst Road traffic over the Jane Addams Memorial Tollway (I-90) and then begin work to reconstruct the bridge that will carry northbound Elmhurst Road traffic over I-90, as well as reconstruction of the existing ramps.

In addition, work is scheduled to reconstruct and widen Elmhurst Road, including the construction of a bridge over Higgins Creek in 2014.

The $54 million Elmhurst Road Interchange Project will complete the existing partial interchange that currently only provides access to and from the east and is scheduled to be completed in 2016. This work is part of the Elgin O'Hare Western Access Project.

Construction Update (09-10-14)

Ramps

The ramps carrying northbound Elmhurst Road traffic traveling to and from the east on I-90 are currently closed. All traffic is routed to the ramps currently used to carry southbound Elmhurst Road traffic traveling to and from the east.

When this phase of ramp construction is completed later this fall, all traffic will be moved onto the newly rebuilt ramps and the other two ramps will then close to traffic to allow for removal and construction of new ramps that will accommodate new access carrying traffic to and from the west.  

Elmhurst Road Bridge

Construction of the new southbound Elmhurst Road Bridge is complete and temporary traffic signals installed. Temporary pavement is being constructed in order to shift traffic in both directions onto the new bridge. This will allow for the demolition the old Elmhurst Road Bridge and the start of construction on the new northbound Elmhurst Road Bridge in late 2014.

On I-90, eastbound traffic between Elmhurst Road and Higgins Creek is shifted to the right to provide a work zone for construction related to the Elmhurst Road Bridge. Traffic is expected to stay in this configuration through the winter.

Project Summary

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. The Elmhurst Road Interchange will be one of the region's first diverging diamond interchanges.

The project includes construction of two new bridge structures to carry southbound and northbound Elmhurst Road traffic over I-90. In addition, existing ramps carrying traffic to and from the east will be reconstructed and new ramps to provide access to and from the west will built.

Additional work on this project includes the reconstruction of the Elmhurst Road Bridge over Higgins Creek and the widening and reconstruction of Elmhurst Road from two lanes to three, which will begin in late 2014 and continue through 2015.

The new southbound bridge is complete and temporary pavement is being constructed in order to shift traffic in both directions onto the new bridge. This will allow for the demolition the old Elmhurst Road Bridge and the start of construction on the new northbound Elmhurst Road Bridge in late 2014.

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 and the Elmhurst Road Bridge will remain open during construction.

In 2014, the Elmhurst Road Bridge Project will require traffic shifts and reduced speed limits on I-90 for work to construct the new bridge structure.

Purpose

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 built in 1958 as part of the original construction of I-90.

The project cost is estimated at $54 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.

Building Green

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

A 45 mph work zone speed limit is in place on I-90. 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.
