The Ohio Department of Transportation awarded the $92.88 million contract for Phase III of the US 33 Nelsonville Bypass, the single largest Recovery Act investment project in Ohio with a total investment of $150 million. The focus of Phase III is on constructing 3.87 miles of four-lane highway. Also included was the construction of the US 33 / SR 78 / SR 691 interchange. The project will reroute SR 78 1.63 miles through the Happy Hollow Area to form the interchange.
Beaver Excavating has excavated more than 3.2 million cubic yards of dirt and embankment since October 2009. A unique construction feature of Phase III includes mine grouting, in which an estimated 500,000 cubic yards of grout is used to fill old abandoned mines in the area.
