WIS 73 - Need/purpose

WIS 73, I-94, I-39 road sign.

Why is this project needed?

Project to increase overall function and safety on WIS 73.

Crash history

  • Deteriorating pavement and numerous geometric deficiencies along WIS 73 have resulted in high amounts of crashes.
  • Crash data from 2005 to 2009 show four key areas that are flagged for improvements:
    • WIS 106 to Craig Rd.;
    • County A intersection;
    • Church Rd. to County B; and
    • Koshkonong Rd. intersection.
  • Two fatalities occurred at the County A intersection between 2010 and 2011 that are likely attributed to the poor visibility at that intersection.
  • There were also two Type A (incapacitating) severity crashes and eleven Type B (bodily injury) crashes along WIS 73 since 2010.

Horizontal and vertical geometric deficiencies

  • Existing horizontal geometry is deficient in five locations along this section of WIS 73 including: Pierce Rd., Craig Rd., East Church Rd. and south of the US 12/18 intersection.
  • Vertical geometry is also deficient at numerous locations along WIS 73. Improvements are necessary to meet current design standards.

Intersection deficiencies

  • Intersection angles at Craig Rd. East and West, and US 12/18, do not meet current standards.
  • Reconfiguration of all intersections along WIS 73 to improve overall mobility and efficiency for through traffic, especially in the event of a major incident on I-39/90 when traffic could be diverted onto WIS 73.

Alternate route for I-39/90

  • WIS 73 continues to serve as an alternate route for I-39/90 to facilitate incident management.
  • WisDOT identified WIS 73 as a potential reliever route for I-39/90 traffic in the event of an incident on the Interstate between Albion and Madison. If a major interstate incident were to occur, traffic could be diverted on WIS 73 to US 12/18.
