Project Information

CTH M (CTH Q to STH 113), Preliminary Design, Dane County

Dane County has contracted with KL Engineering to initiate the environmental and design phases for improvements proposed to CTH M from CTH Q to STH 113 in Dane County. The existing roadway is highly congested, especially during weekday commuter travel times.  Residential and commercial development is planned along and near the corridor, traffic volumes are expected to increase along with congestion and potential safety issues.

KL Engineering will be investigating a range of options for improving the safety and capacity of CTH M, which may include a 4-lane expansion alternative.  Bike lanes, shared-use facilities and transit routes are being considered throughout the length of this project.  Improvements to several intersections and new bridges or expansions to existing structures is also anticipated. The City of Middleton, Village of Waunakee and Town of Westport are also providing input in the project design.

Project development is currently underway. Public Involvement Meetings are expected in the Fall of 2018 and the Spring and Summer of 2019.  Final design will begin after this phase of the project is completed. Construction has yet not been scheduled.

A design schedule and project location map, along with Frequently Asked Questions, are attached.
