Last Updated: 07/13/2020

Latest Update

7/13/2020:

The majority of the work on the south side of Cottage Grove Rd., including the lower layer of asphalt pavement, is now complete.  The bore and placement of the new 20" water main under the Interstate is also complete. On Monday 7/13, the Contractor will be working to switch traffic from the north side over to the newly constructed south south of Cottage Grove Rd.  Once the traffic has been switched over, they will begin removals and milling of the existing asphalt pavement the north side.  By around the end of the week, they will begin work on the water main connections, which will mostly be located at the intersections, and they will also begin work on the storm sewer along the north side of Cottage Grove Rd.  The utility work on the north side will continue through the end of the month.  In coordination with the utility work, the Contractor will also work on grading the new roadway for the westbound lanes.

Once the traffic switch is complete, one lane of traffic in both directions will remain on the south side of Cottage Grove Rd. until near the end of the project, and the intersection of Cottage Grove Rd. and Sprecher continues to function as an all-way stop.

Project Overview

The City of Madison in conjunction with Dane County and the Wisconsin Department of Transportation is proposing to reconstruct portions of Cottage Grove Road within the City of Madison. The construction schedule for the project has been revised and the first phase of the project is now scheduled for construction in 2020. The first phase of the project includes reconstruction of Cottage Grove Road from the east side of I-39/90 to South Sprecher Road. The second phase of construction includes the reconstruction of Cottage Grove Road from South Thompson Drive to the east side of I-39/90 and will include the replacement of the Cottage Grove Road overpass of I-39/90. The construction year of the second phase of the project is not currently known but will coincide with the WisDOT’s replacement of the I-39/90 overpass.

The proposed project will reconstruct Cottage Grove Road to a four lane, urban boulevard section.  The proposed street layout will include two through lanes and on-street buffered bike lanes in each direction, with a raised center median and left turn lanes at intersections. The reconstruction of the street will include the replacement of the pavement, base material, curb and gutter and drive aprons. Sidewalk will be added where it currently does not exist. The proposed project will also include construction of water main and storm sewer as well as improvements to the street lighting and traffic signal systems.
