Project location

South Towne Drive/W. Broadway bridge over US 12/18 (Madison Beltline), Madison - Dane County

Project overview

This project will make structural repairs and place a concrete overlay on the bridge deck. Construction will start 150 feet south of US 12/18 and extend over the bridge to 115 feet north of US 12/18.

Improvements include:
  • Replace expansion joints (joints built into bridge surface, so it can expand and contract)
  • Replace concrete pavement between the ramp terminals
  • Replace lighting on the ramps
  • Install new traffic signals


  • October 23, 2019 - Public involvement meeting (PIM)
    • 5 - 7 p.m.
    • Badger Rock Middle School, 501 E. Badger Road, Madison
    • Meeting will familiarize local residents and businesses with the purpose and need for the project and provide specifics on traffic impacts during construction
  • April 2020 - Construction anticipated

Traffic impacts/detours

Turning movements will be restricted at the South Towne Drive interchange.

  • The eastbound off ramp will maintain full functionality throughout the project.
  • The other three ramps will only allow right turns.
    • For instance westbound off ramp from US 12 will only be able to turn right at South Towne Drive.

*Sidewalk will need to be added along the west side of South Towne Drive, to accommodate pedestrians during construction staging.
