WIS 73 - Need/purpose
Why is this project needed?
Project to increase overall function and safety on WIS 73.
- 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 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.
