Project location

US 51 (Stoughton Rd.), Terminal Dr./Voges Rd. (McFarland) to WIS 19 (DeForest), in Dane County

Project overview

This is an Environmental Impact Statement (EIS) study that will develop and evaluate long-term alternatives to address the safety and congestion issues along the corridor. It will also evaluate gaps in bicycle and pedestrian facilities along the corridor.

The primary function of US 51 in the Madison area is as a regional and local traffic carrier. Regional trips are those that pass through, but are not destined for, a given location such as the city of Madison. Local trips begin and/or end somewhere near or along the corridor and involve turns on and off of US 51. As volumes of both types of traffic continue to increase, the ability of US 51 to efficiently serve these two conflicting uses has declined.

Study background

This segment of US 51 has three components, two of which have been completed:

  • Environmental Impact Statement (EIS)

    • In November 2011 the Stoughton Road corridor was approved by the Transportation Projects Commission as a Major Project study candidate and the EIS study began. Currently WisDOT is evaluating a Phased Implementation (construction) approach for the corridor.

      The Phased Implementation approach will identify sections of the corridor for construction as well as potential timeframes, or phases, for construction of those sections. It is possible that interim improvements may be needed for sections of the corridor in subsequent phases in order to meet the project purpose and need until construction of those phases can occur.
  • Traffic, Safety and Needs Identification Analysis (TSNIA)

    • Completed 2012, this study developed possible long-term corridor solutions to address the problems identified in the Needs Assessment (NA).
    • Capacity expansion was not investigated as part of the TSNIA, however all alternatives were designed to accommodate an additional lane in each direction.
  • Needs Assessment (NA)

    • Completed June 2003, this study determined the existing roadway's condition and how future traffic volumes will impact traffic flow.
    • The NA indicated there was sufficient need to study potential improvement alternatives.

No major construction projects are planned at this time.

Future (next year and beyond)

  • Public involvement meeting (PIM) - Date to be determined
  • Draft EIS (DEIS) completed - Date to be determined
  • Public Hearing on DEIS - Date to be determined
  • Fall 2022
    • Final EIS (FEIS)
    • Record of Decision (ROD) anticipated

Past (anything prior to today)

2014 - 2017

  • Meetings with various property owners/stakeholders along the corridor 


  • Meetings with various property owners/stakeholders along the corridor
  • March 19, 2013 - PIM, presented updated alternatives



  • Environmental Impact Statement (EIS) Study - Long-term planning with no scheduled construction activity.
  • Study scheduled to be completed in the fall of 2022.
