Illinois Route 390 Tollway

Elmhurst Road Interchange Project at I-90

Construction Update (03-27-17)

On Monday, April 3, Elmhurst Road traffic south of the interchange will be reduced to one lane in both directions for pavement removal and replacement. This stage of construction is schedule to continue into mid-May.

During the week of April 3, traffic on Oakton Street and Elmhurst Road will be reduced to one lane in each direction to complete intersection and local road work. Traffic is scheduled to remain in this configuration until work is completed this summer.

Currently, the ramps carrying traffic to and from the east are open to traffic with the ongoing construction work zone adjacent to Elmhurst Road.

Traffic shifts will be ongoing to complete installation of new permanent, traffic signals, lighting and pavement markings necessary to safely open the interchange in the new diverging diamond configuration.

Project Overview

The $54 million Elmhurst Road Interchange Project on the Jane Addams Memorial Tollway (I-90) will complete the existing partial interchange that currently only provides access to and from the east. In 2017, the Illinois Tollway will complete work to open new ramps and the new diverging diamond interchange configuration. Work also includes reconstruction and widening of Elmhurst Road and improvements to the intersection of Elmhurst Road and Oakton Street. This work is part of the Elgin O’Hare Western Access Project.

The Elmhurst Road Bridge Project will require traffic shifts and ramp closures to complete the conversion to the diverging diamond interchange configuration.

Project Live Images

The Illinois Tollway is constructing a new interchange at Elmhurst Road on the Jane Addams Memorial Tollway (I-90) as part of the Elgin O'Hare Western Access Project. The Elmhurst Road Interchange will be one of the first diverging diamond interchanges constructed in the region.

The live images of the construction site show ongoing work to reconstruct the bridge carrying northbound Elmhurst Road traffic over I-90 while traffic in both directions travels along the new bridge carrying southbound Elmhurst Road traffic over I-90.


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 access only. These ramps were built in 1958 as part of the original construction of I-90.

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.

All of the existing pavement on Elmhurst Road, as well as ramp pavements will be recycled into the new pavement or asphalt mixes.

Work Zone Safety

The Illinois Tollway is committed to ensuring that the Jane Addams Memorial Tollway (I-90) and Elmhurst Road remain safe for both drivers and workers during construction, which is part of the agency’s overall commitment to roadway safety.

A 35 mph work zone speed limit is in effect on Elmhurst Road. On I-90 a 45 mph work zone speed limit is in effect throughout the construction season.
