Highway 371 Expansion, Minnesota, United States of America
Located in central and north-central Minnesota, US, State Highway 371 links the state's northern lakes region with the central region. The highway is being expanded from two to four lanes from Nisswa to Jenkins to improve access along the corridor.
The $58m expansion is being undertaken by the Minnesota Department of Transportation (MnDOT).
Construction on the project commenced in April 2016 and is scheduled to be completed by mid-2017.
Highway 371 expansion project purpose
The Highway 371 improvement project is aimed at providing transportation system improvements to resolve critical travel safety, design deficiencies and capacity problems, as well as reduce congestion.
The alternatives for Highway 371 improvement included no built, existing alignment, existing alignment with Pequot Lakes bypass, existing alignment with Pequot Lakes and Jenkins bypass, and existing alignment with Jenkins bypass.
The existing alignment with Pequot Lakes was selected as the preferred alternative for the highway expansion. MnDOT completed the draft supplemental final environmental impact statement for the alternative in February 2010. The supplemental final environmental impact statement (SFEIS) was completed in July 2010. Property acquisition for the project was completed between 2010 and 2015.
The plans for the expansion of Highway 371 between Nisswa and Jenkins were announced in October 2014 after obtaining $45m under the Corridors of Commerce funds.
Highway 371 expansion project details
The project will expand a nine-mile (14.48km) section of the Highway 371 between Nisswa and Jenkins to four lanes from the existing two lanes.
The project will add lanes of road and construct a new Cullen Brook bridge in the Nisswa region.
In the Pequot Lakes region, the expansion involves construction of two lanes of road and realignment and addition of easy access points to city roads. A new County Road (CR) 11 interchange with roundabouts will also be constructed, as well as new road links at CR 168/107 and CR 112.
Construction works in the Jenkins region involve a new signalised intersection at CR 16/Meyers Road. The project will also realign the Paul Bunyan Trail and add a new trail bridge over the highway in Pequot Lakes.
