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 side streets reduced to one lane in each direction throughout most of the construction duration.

Construction Status

Temporary Traffic Signals are in operation at 55th Street/Main Street.
Temporary Traffic Signals are in operation at 55th Street/Fairview Avenue.
During the 2019 construction season, traffic was in the Stage 1 configuration only between Dunham Road and Fairmount Avenue, with the north lane closed and 55th Street in a 3-lane configuration through this area, one lane open in each direction separated by a two-way left turn lane.  Main Street was also in a 3-lane configuration.  The north side widening at Main Street was completed this season, along with miscellaneous curb and gutter and sidewalk repairs, but the Stage 1 work at Fairview was not started due to utility work.
The original traffic configuration was restored in late December 2019 for the winter period. 
On April 3, 2020 the 3-lane configuration was again partially implemented to continue the work.
Manhole frames from have been removed from the roadway area, and milling (grinding) the asphalt for subsequent resurfacing has also been completed.  The manhole frames will be re-set after the first layer of asphalt are completed.
The first layer of asphalt is currently being placed.
Current work activities also include retaining walls, driveways, traffic signals, and landscape restoration.

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's work is substantially complete.
Comcast's work is substantially complete.
ComEd had about 20 utility poles to relocate along with the overhead lines, as well as some underground ducts and cables.  ComEd's work is substantially complete.
MCI/Verizon's work is substantially complete.
Nicor had 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.   Nicor's work work is now substantially complete.
WideOpenWest's work is substantially complete.
