Armstrong Boulevard Interchange (US Highway 10 and CSAH 83)

Anoka County, Minnesota

With eventual build-out of the COR Development, a multi-phase transit-oriented development focused around the Ramsey Northstar Station, the projected traffic at the intersection of US Highway 10 and Armstrong Boulevard (CSAH 83) demanded a new grade-separated interchange.  As the  final design consultant, SRF engineered the overall layout that includes two bridges, seven retaining walls, approach ramps, two new signalized intersections, and a pedestrian/bicycle path. Working closely with Anoka County, SRF coordinated the project design with other key stakeholders, including the City of Ramsey, BNSF Railroad, utility companies, and property owners.  SRF also prepared detailed renderings to communicate the proposed design features with key stakeholders and the public.

The new overpass bridges are prominent landmarks across US 10 and the BNSF Railroad, with enhanced architectural detailing that complement the City’s civic identity. A generous pedestrian/bicycle path across the bridges  connects the COR Development to a residential neighborhood and recreational areas along the Mississippi River to the south. The Armstrong Boulevard Interchange is a key link in the northwest metro’s transportation network.
