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
WIS 106 to Craig Rd.;
County A intersection;
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
There were also two Type A (incapacitating) severity
crashes and eleven Type B (bodily injury) crashes along WIS 73 since
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.
