The team, which included us along with five other national and regional consultants, was selected to support MnDOT District One with the oversight verification of the design and construction for the relocation of TH 53 over the Rouchleau Pit in Northern Minnesota. TH 53 had to be relocated due to the expiration of an easement agreement with the local taconite mining company and thus a new alignment was created to accommodate the relocation over Rouchleau Pit. The pit is approximately 250 feet deep at the crossing location and the bridge spans approximately 1,100 feet with 180-foot or taller bridge piers within the pit.

This project is the second Construction Manager/General Contractor (CMGC) in Minnesota and required special attention to the plans for compliance in order to be approved by MnDOT Central Office staff. We, along with the design team and construction team, kept this project on track for a 2017 completion and allowed the mining company access to their minerals that are currently underneath the existing TH 53.
