Location: Thief River Falls, MN
Client: Pennington County Highway Department
The growth of Thief River Falls is expected to increase along the southern boundaries in the coming years with the expansion of businesses and entities like the Sanford Medical Center, the Thief River Falls Airport, Challenger Elementary School, Digi-Key, and Arctic Cat, all of which are critical facilities to the city’s economy.
However, east-to-west connectivity within this area is limited, restricting efficient access to this southerly growth. New and updated corridors for increased traffic types and volumes needed to be evaluated to allow the city to continue to thrive for years to come.
HEI assisted the Pennington County Highway Department in providing conceptual studies, roadway/bridge design and construction documents, public engagement, environmental permitting, and construction assistance for the new corridor including a new river crossing, roadway, and intersection improvements.
The new roundabout and corridor improvements enhance traffic flow, safety, and connectivity within the growing areas of Thief River Falls, MN.
HEI also teamed with a partner to bring our complementary qualifications and experience together to best serve the community. Through this partnership, two build alternatives and a no-build alternative were evaluated and scored. HEI kept in mind the needs for the project, including efficient access for business and residential expansion. Our team recommended a build alternative creating a new river crossing and street corridor allowing for businesses and residential growth for these areas.
HEI and its partners developed a project that included the construction of a new 1-mile street corridor, a new bridge, and two new roundabouts, each at major intersections. Construction was completed and the facilities were fully operational by the fall of 2020.
The completed new bridge crossing.
The Pennington County Highway Department hosted a bridge dedication/ribbon-cutting ceremony in July 2021.
