Due to the expiration of a temporary easement with the local mining company, it was determined that TH 53 in Virginia and Eveleth had to be relocated. The Federal Highway Administration’s Construction Manager/General Contractor (CM/GC) project delivery method was selected as the best process to complete the project due to the tight project timeline agreement. MnDOT selected WSB to provide the design and oversight verification, lead the environmental compliance work, and assist with acquisition and relocation services.
The selected alternative directs a 3.2-mile reroute of Highway 53 over the Rouchleau Pit on a 1,132-foot-long, four-lane welded steel girder bridge. Given these parameters, there was a significant amount of grading and earthwork quantities - almost one million cubic yards of excavation and more than 600,000 cubic yards of embankment - that needed to be accounted for as part of providing the bridge crossing.
This project is the second Construction Manager/General Contractor (CM/GC) in Minnesota and required special attention to the plans for compliance. When completed, it will be the tallest bridge in Minnesota: the distance from the deck to the water is close to 200 feet.
