TH 371 Reduced Conflict Intersection

Brainerd, MN

Project Overview


The TH 371 Reduced Conflict Intersection (RCI) project was undertaken to improve access and safety at three critical intersections along this heavily traveled corridor in the heart of Minnesota lake country. The project area included planning and coordinating access to the Brainerd International Raceway, which is a destination for large events throughout the year and a key point of tourism in the area.

Our Work

Isthmus led both the preliminary and final design work for this corridor safety improvement project. Drawing on past project experience with District 3 and an understanding of district standards and community needs, our team designed three new RCUTs along TH 371 at Gull Lake Dam Road (CR 125), Green Gables Road (CR 126), and the access to Brainerd International Raceway at Birchdale Road.

The project’s critical challenge was to incorporate multiple needs within a constrained and busy space. Our team determined how to design and construct three consecutive RCUT intersections along the 1.5-mile corridor, including new frontage roads and business accesses, while coordinating with utility companies and keeping traffic flowing during the heavy travel season. The RCUT intersections essentially needed to “bump” into each other and the addition of the RCUTs and frontage roads reduced space for utilities.

Our work in the preliminary design phase included geometric layouts, hydraulic analysis, and utility relocation analysis. During the final roadway design process, our team led 3D modeling, utility coordination, hydraulic and drainage design, and final signing and pavement marking plans.
