WIS 164 (County Q to County E) Rehabilitation - 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.
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 information 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
Insufficient sight distance at several hills and
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.
