The TH 371 Four Lane Expansion Project converted 10 miles of two lane highway into a four-lanes on a route that extends from Nisswa, through Pequot Lakes and ending in Jenkins. The $50 million project included the construction of three bridges, an interchange with roundabouts, two reduced conflict intersections and the realignment of the Paul Bunyan Trail. Earthwork was a major component of the project, requiring two million cubic yards of material to be moved. Innovative 3D modeling of the moved material was developed in our office and deployed to the road graders and dozers, resulting in an efficient office-to-field operation.
As part of the Mathiowetz Construction Company (MCC) Team, we served as the lead design firm managing the design and construction quality for the project. The design services included roadway engineering, hydraulics engineering, structural engineering, traffic engineering, environmental engineering, surveying, project controls and construction quality management.
