About The Project

The interchange at Interstate 29 (I-29) and 40th Avenue North has been experiencing significant traffic growth due to new development along both sides of I-29. This includes development west of I-29 in the Reile’s Acres residential subdivision, additional land that will become available following the completion of the Fargo-Moorhead Flood Diversion, and industrial development east of I-29.

To address increased roadway capacity and safety concerns, NDDOT completed a feasibility study in summer 2023. The recommendation from the study was to reconstruct the interchange with two roundabouts at the ramps as shown below. The intersection of 40th Avenue North and Old County Road 81 will also be reconstructed as a roundabout.

The project is now in the preliminary design and environmental documentation phase as shown under “Project Schedule”.

Recommended interchange alternative from the 2023 feasibility study.
Dumbbell interchange identified as the alternative to advance to the next phase of project development.
