Road work preparations begin this week in Moorhead for 11th Street underpass project

DETROIT LAKES, Minn. – Beginning the week of March 18, weather permitting, contractor crews will begin working on initial tasks and preliminary preparation work for the 11th Street underpass project, according to the Minnesota Department of Transportation. Crews will start road work preparation, building demolition and other miscellaneous activities throughout the project area.

Traffic impacts during the week of March 18 are expected to be minimal, but motorists and pedestrians should be prepared for some restrictions or intermittent traffic shifts.

Then, starting the week of March 25, initial Stage 1A closures and detour will begin. First Avenue will close between 10th Street and 12th Street, and 11th Street will close between First Avenue North and Second Ave North. Traffic will be detoured to 14th Street North, Fourth Avenue North and Ninth Street North.

The 11th Street underpass project includes construction of two underpasses on 11th Street under the BNSF rail lines, as well as paving, sidewalk improvements, utility replacements and signals. The project will provide safety and mobility benefits by removing blockages caused by heavy rail traffic. The work will be completed in stages starting March 2024 through November 2026.

Ames Construction, based in Burnsville, Minn., is the prime contractor for the $122 million project. For more information and to sign up for project progress emails, visit mndot.gov/d4/projects/moorhead11thstreetunderpass.
