Potters Mills, Route 322

Location Potters Mills, PA


Owner: PennDOT District 2-0


Construction Costs: $4.68 million


Duration July 2018 – May 2019

Wagman’s Geotechnical Construction group is supplying the geotechnical construction needs for the Potters Mills project in Centre County, Pa. The $4.68M project consists of the widening and realignment of state Route 322. The contract is for a design-build of approximately 50,000 SF of soil nail slope treatment with wire mesh, nearly 12,000 SF of temporary support of excavation and installation of roughly 40,000 SF of rock fall mesh. When the project is complete, it will relieve congestion from what has been a natural bottleneck for decades, and it will bypass an intersection that has been busy and difficult to navigate.

Key Challenges & Project Details

  • Heavily traveled roadway. The project is located on a major access road to Penn State University.
  • Project features include three soil nail walls, two rock fall mesh walls and two temporary support of excavation walls.
  • Difficult access on steep slopes. Wagman and the general contractor managed to excavate and dig two rows of nails at once to create a large enough bench and ramp to access the work area on the project.
