Project Location(s)

County Highway 35     55th Street
Between Maple Avenue/Dunham Road and Williams Street

Short Description of Work

The project includes widening the intersection of 55th Street / Main Street to add a left turn lane in each direction, widening the intersection of 55th Street / Fairview Avenue to add left turn lanes along 55th Street, reconfiguring Fairview Avenue to include left turn lanes without widening the pavement; some water main replacement; storm sewer improvements; retaining walls; sidewalk improvements; traffic signal replacements at 55th/Main, at 55th/Fairview, and at the fire station on Main Street; traffic signal interconnect to Clarendon Hills Road; and pavement resurfacing.  Access to Webster Street north of 55th Street will be eliminated, and left turns will be prohibited to and from Webster Street south of 55th Street.  Left turns will be prohibited to and from Washington Street.

This project is a joint effort between DuPage County, the Village of Downers Grove, and the Illinois Department of Transportation.

Traffic Control

The project will be constructed in several stages, with 55th Street and sidestreets reduced to one lane in each direction throughout most of the construction duration.

Contract Cost


Completion Date

110 Working Days are allowed per the special provisions.

Construction Status

Construction has started with minor items such as fence removal and installation of erosion control measures.  Water main work is expected to start around April 1st.  Contractors for Nicor have started working to install new gas mains.  Webster Street north of 55th Street will be closed starting March 25th.  

Although relocation of utility facilities is required and the DuPage County Division of Transportation issues permits to the utilities within the Right-Of-Way, the D.O.T. does not directly control the work of the various utilities.
AT&T mostly has adjustments to do along Main Street.
ComEd has about 20 utility poles to relocate along with the overhead lines, as well as some underground ducts and cables.
Nicor has gas mains to relocate or replace along both sides of the roadway, totaling more than 2 miles of gas main ranging from 2 to 12 inches in diameter.
