TH 53 Bridge CM/GC

Construction Cost: $156M

Contractor: Kiewit
Owner: MnDOT

Design/Construction Dates: April 2015 to November 2017
Contract Duration: April 2015 to Present

Role: WSB provided the construction oversight for this project and represented MnDOT.  Responsibilities included design review, contract administration, inspection, materials sampling and testing, environmental compliance schedule review, change management and overall responsibility for the project’s construction.

Summary: The team, which included WSB and five other national and regional consultants, was selected to support MnDOT District One with project administration, design and construction for the relocation of TH 53 over the Rouchleau Pit in northern Minnesota. TH 53 had to be relocated due to an expiring easement agreement with the local taconite mining company and thus, a new alignment was created to accommodate the relocation over Rouchleau Pit. The pit was approximately 250 feet deep at the crossing and the bridge spaned approximately 1,100 feet with 180-foot, or taller, bridge piers within the pit. The rock excavation for this project was extensive and the contractor was able to incorporate all the material that was mined back into the project and incorporated into a variety of applications including fill, aggregate base and concrete.

This project was 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. WSB, along with the design and construction teams, kept this project on track for a 2017 completion while allowing the mining company access to their minerals underneath the existing TH 53.
