The 55th Street Grade Separation project was a key component of a broader infrastructure effort connecting US Highway 2 East with US Highway 83 North. This improvement created a vital transportation link on the eastern edge of Minot, North Dakota, supporting regional growth and long-term mobility.
Supporting Freight and Agricultural Development
With projected increases in truck traffic and industrial development, the project was designed to enhance the safe and efficient operation of these heavily used corridors. A primary challenge was creating a reliable grade separation to eliminate conflicts with freight rail activity on the BNSF Railroad mainline.
SRF provided bridge design and engineering services, delivering a 1,155-foot bridge structure spanning the active BNSF rail line. The design ensures continuous access while improving safety for all users.
Retaining Wall and Structural Engineering
To accommodate elevation changes at the site, SRF also assisted in the design of a mechanically stabilized earth (MSE) precast panel retaining wall on the south bridge approach. The wall supports the new roadway and integrates seamlessly with the surrounding infrastructure.
SRF was also involved in construction oversight for the project, assisting with surveying, inspection, and technical assistance as required.
By improving freight movement, reducing delay, and increasing safety, the 55th Street Grade Separation is a foundational investment for the region’s evolving transportation network.
