DOT installs high friction surface treatment on portion of Holy Hill Road
WASHINGTON COUNTY — Crews with the Wisconsin Department of Transportation on Thursday, June 2nd began installation of a high friction surface treatment (HFST) on WIS 167 (Holy Hill Road) in Washington County.
The approximate project limits are from Friess Lake Road to a half-mile east of Friess Lake Drive.
According to a release from the DOT, crashes in that area are well above the statewide average. Contributing to some of the collisions are the sharp curves that are slick during rain and snow events. Adding the HFST to the two curves will increase traction for vehicles.
To increase safety, temporary portable rumble strips have been laid down to alert motorists they are entering a work zone. This is the first WisDOT Southeast Region improvement project to use these devices.
Ninety percent of the $124,000 project is paid for by the federal government, the remaining ten percent being paid for by the state. The project is funded through the Highway Safety Improvement Program which focuses on low-cost improvements at sites that have experienced a high crash history.
HFST is a specially-engineered pavement overlay that has a rougher texture and greater surface area to provide additional friction. The benefits of HFST are as follows.
- Reduce crashes, injuries and fatalities
- Relatively low in cost compared to geometric improvements
- Produce negligible environmental impacts
- Short installation time has minimal impact on traffic
