The purpose of the maintenance and roadside improvements will provide the traveling public with a safe and smooth riding surface.​

WisDOT is in the process of developing plans to repair deteriorated pavement on US 18/151 and adjacent ramps. The project will include concrete base patching and an asphalt overlay. The project will also include an extended right turn lane along the westbound off ramp to County PB.​
