Highway 14 between Owatonna and Dodge Center, Minnesota sees 18,000 travelers daily and has experienced congestion and safety concerns. Mead & Hunt served as the prime consultant on the Minnesota Department of Transportation’s Construction Verification Team to provide oversight and inspection for the expansion of this corridor, leading to a successful delivery.
This $108 million design-build project constructed the last 12.5 miles of highway expansion from two lanes to four lanes. This completed a continuous four-lane roadway between Rochester and Mankato in order to improve capacity, safety and travel times. The highway was constructed along a new alignment parallel to a Canadian Pacific Railroad, increasing safety by eliminating over a dozen at-grade railroad crossings. Major construction elements included two million yards of excavation, five new bridges, base aggregates, concrete and asphalt pavement, environmental and storm water considerations, building demolition, railroad coordination, box culverts and culvert pipes, settlement monitoring and erosion control.
