As two steel bridges began to corrode on Highway 57, outside of Mantorville, MN, the Minnesota Department of Transportation coordinated their six-month replacement. MnDOT relied on County Prestress & Precast's Prestressed Bridge Girders to meet the construction schedule and provide unmatched longevity. Thirty girders were manufactured, measuring 34’ to 63’ long. County Prestress & Precast played an integral role in the success of this multi-bridge replacement project, partnering with Icon Constructors from shop drawings through girder installation.
