WIS 164 Rehabilitation (County Q-County E) - Need/purpose

Why is this project needed?

The WIS 164 project is approximately 7.5 miles in length and extends from just north of County Q to just north of County E in Washington County (see location map). The goals of this project are to improve safety and pavement conditions.

Pavement rehabilitation

The existing full depth asphalt pavement was constructed in 1964 and was last resurfaced in 2000. The pavement is currently showing signs of wear and distress and is expected to continue to deteriorate.


This segment of WIS 164 has a crash rate that is 67 percent higher than the statewide average for rural two-lane state highways. There have been a total of 74 reportable crashes between 2007 and 2009 within the project limits, which excludes deer crashes. Of those 74 crashes, two have involved fatalities and 35 have involved injuries. The percentage of crashes classified as injury crashes was 47 percent, which is 23 percent higher than the statewide average for rural highways. This means that almost one of every two crashes on WIS 164 results in an injury.

Deficiencies in the project corridor

The existing roadway features, crash data, and public input were studied in detail following the first Public Involvement Meeting. Several key deficiencies were identified that contributed to the higher than average crash rate and crash severity for similar rural state trunk highways, and correlate to areas of concern raised by public comments.

  • Insufficient sight distance at several hills and intersections
  • Lack of turn lanes as most intersections
  • Long waits and delays at WIS 167 (Holy Hill Road) intersection during rush hours and weekends
  • Steep slopes off the shoulders, leading down to the ditches
  • Steep grades along entire corridor

Other deficiencies were also identified throughout the corridor that were not associated with a pattern of crashes. Low impact improvements, such as new or improved guardrail installations and new roadway signing and pavement marking are proposed in these areas.
