U.S. Trunk Highway 53 Girder Design
Parsons provided the Minnesota Department of Transportation (MnDOT) the design for a new bridge and roadway between the iron mining cities of Virginia and Eveleth, MN. The existing Highway 53 was on a 1960 easement that expired in 2017 necessitating MnDOT to relocate the highway to allow mining operations to continue. To meet the project deadline the bridge was designed and built under an accelerated schedule utilizing the Construction Manager/General Contractor (CMGC) delivery method. Parsons is the Engineer of record for the new 1,130-foot three span steel plate girder bridge, with a 480 foot long main span, 180 feet above the floor of the Rouchleau mine. Overall project services include project management, preliminary and final bridge design and plans, shop drawing review, bridge load rating and roadway design services for the relocation of Highway 53.
