USH 18/151 (Town Hall Road to Fitchrona Road)

Hwy 18/151, a WisDOT project between Mount Horeb and Fitchburg, WI, involved resurfacing 48 lane miles and six interchanges along the USH 18-151 corridor in Dane County. The project used approximately 200,000 tons of asphalt, including 60,000 tons of stone matrix asphalt (SMA) surface.

US Highway 18/151, a major roadway, had deteriorated and required maintenance to prolong its lifespan. The project aimed to provide drivers with a safe and smooth road surface. This involved concrete base patching, asphalt overlay, and extending the right turn lane on the westbound off-ramp to County PB. Walbec's P+D and Parisi teams collaborated on the project, with P+D responsible for asphalt-related work and Parisi managing the mainline concrete pavement.

P+D's milling, grading, and paving crews started working on the project in April 2023 and completed it in late November. The project was divided into two large stages, each covering six miles, and long-term lane closures were allowed during the active stage.

The project received the 2023 State Asphalt Award from the Wisconsin Asphalt Pavement Association (WAPA) for its innovative practices in completing a large highway project within a single construction season.
