Project Overview

Illinois Route 56 (Butterfield Road)
West of Illinois Route 59 to Naperville Road
City of Wheaton and City of Warrenville
Roadway Reconstruction, Additional Lanes, Bicycle Accommodations, and Utility Adjustments

Project Background

The project was initiated to address safety, congestion, and mobility along this highly traveled State route in DuPage County. The proposed improvement was intended to not only address mobility issues, but was also required to sustain regional commercial development and to improve access to existing local retail centers and residential areas.

Project Purpose

The proposed project will provide a safer roadway facility with a lower accident potential and improved access management. The existing Average Daily Traffic (ADT) along certain portions of Illinois Route 56 exceeds 26,000 vehicles per day.

Project Scope and Cost

The proposed improvement will include reconstruction of Illinois Route 56 (Butterfield Road) from just west of Illinois Route 59 to Naperville Road from an existing 2 lane highway to a 4 lane divided highway with a 30 foot grassed barrier median. Major intersections within the project limits will be improved by adding turning lanes, increasing queue storage lengths, providing standard taper rates and modernizing traffic signals to address safety and capacity deficiencies. In addition, the traffic signals along the corridor will be interconnected. The structure carrying Illinois Route 56 over the West Branch DuPage River will be removed and reconstructed. The structure carrying Illinois Route 56 over Ferry Creek will also be removed and replaced with a double box culvert. Also, a total of 1,081 trees will be planted along the project.

Start Date / Completion Date

Construction would begin in spring 2011 with an anticipated completion date of November, 2012. The first phase of the construction staging will concentrate on constructing the two proposed southern lanes of Illinois Route 56 at which time the existing northern two lanes will remain open to traffic. After construction of the southern lanes traffic will shift to the southern lanes to enable reconstruction of the existing lanes.

Job Retention/Creation

Approximately 910 jobs will be retained or created.
