WIS 21 Coloma/Wautoma

Location

WIS 21, Madison Street to WIS 22, Waushara County

Overview

WisDOT identified several needs along this 13-mile segment of WIS 21:

  • The pavement is experiencing extensive block cracking and a significant amount of rutting and has reached its useful lifespan
  • Sight distance restrictions exist at the WIS 21 and County B intersection due to the hill directly west of the intersection
  • Run off the road crashes have occurred within the project limits
  • The guardrail has reached its useful life and needs replacement
  • Four culverts require replacement

Proposed improvements

WisDOT plans to replace the pavement with new asphalt with the following process:

  • Pulverize and relay – uses the old pavement for the base prior to applying new asphalt

Other improvements to address the needs include:

  • County B intersection improvements
      • Reconstruct WIS 21; lowering the hill approximately 13' to improve sight distance
      • Realign the south leg of County B to match into the north leg
  • Spot slope grading to flatten steep slopes
  • New guardrail
  • Centerline rumble strips
  • Pavement safety edge
  • Culvert replacements at four locations
  • Widening of paved shoulders for bicycle accommodations from three feet to five feet
    • Madison St. to 6th Avenue
    • Oakdale Court to WIS 22

The proposed improvements will provide a smoother ride, improve safety and maintain drainage.

Traffic impacts during construction

  • WIS 21 will be closed and detoured for approximately three months in summer of 2021.
  • Detour will be I-39 to WIS 73 to WIS 22 (see detour map)
  • WIS 21 will be open to local traffic with spot closures at culvert replacement and hill grading locations

Real Estate

  • Strip acquisitions will be needed for work at the County B intersection as well as the spot slope grading locations.
  • WisDOT expects to begin real estate acquisition in summer of 2020.

Schedule

  • Finalize design – November 2020
  • Construction is currently scheduled for 2022, but could occur as early as 2021.
