Cottage Grove Road (I39 to Sprecher Rd)
Last Updated: 03/12/2019
Dane County will be replacing a failing storm culvert east of Sprecher Road on Tuesday, October 30th. Cottage Grove Road will be closed to through traffic at the culvert location on the 30th between 7 a.m. and 6 p.m. Please adjust your travel plans accordingly while this repair is being made.
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.
