Milhouse provided construction management services for the reconstruction of the Elmhurst Road Interchange along the Jane Addams Memorial Tollway (I-90). The work is part of the Elgin O’Hare Western Access Project.
The interchange reconstruction involves the conversion from a partial cloverleaf with access to and from the east to a diverging diamond interchange with full access. The reconstruction comprises three contracts: the construction of the two Elmhurst Road bridges over mainline I-90; the widening of Elmhurst Road to six lanes over a one-mile stretch; and the reconstruction of the Elmhurst Road/ Oakton Street intersection to the north of the interchange.
The project includes construction of two new bridge structures to carry southbound and northbound Elmhurst Road traffic over I‐90. The new bridge features a shared use path for pedestrians and bicyclists in the median of the northbound bridge. In addition, existing ramps carrying traffic to and from the east will be reconstructed and new ramps will be built to provide access to and from the west. Additional work includes the reconstruction of the Elmhurst Road Bridge over Higgins Creek, as well as the reconstruction and widening of Elmhurst Road from two lanes to three.
The project requires coordination with the I-90 corridor manager; the Elgin-O’Hare Western Access corridor manager; the City of Des Plaines; the Village of Mount Prospect; the Village of Elk Grove Village; several major utility companies with large utility lines in the project vicinity; the Illinois Department of Transportation; and the Federal Aviation Administration, due to the project’s proximity to O’Hare International Airport. In addition, the project includes green features that minimize the environmental impact of construction. New asphalt pavement used for the ramp shoulders incorporates materials such as warm-mix asphalt, reclaimed asphalt pavement, and recycled asphalt shingles.
The project cost is an estimated $54 million and is part of the Tollway’s 15-year, $12 billion capital program, Move Illinois: The Illinois Tollway Driving the Future.
