Project ov​erview

The Wisconsin Department of Transportation (WisDOT) is developing preliminary plans for a High Friction Surface Treatment (HFST) on the bridge deck on US 18/151 eastbound over South Jones Street as planned preventative maintenance to extend the service life of the bridge. Along with the bridge repairs, WisDOT is developing preliminary plans for a HFST for seven pairs of curves along US 18/151 to decrease the number of run-off-the-road crashes. Additionally, there are four bridges within the curve limits that will also receive a HFST.
