4th Street South and Main Avenue Intersection Closes to all Traffic Beginning April 29


Next week crews for the North Dakota Department of Transportation (NDDOT) and City of Fargo Main Avenue reconstruction will begin work at one of the major intersections planned to be reconstructed between the Red River Bridge to Broadway in the first year of downtown Fargo infrastructure improvements.

Starting, Monday, April 29 by 7 AM, the second traffic shift will begin on Main Avenue. Crews will fully close the Main Avenue and 4th Street South intersection to all directions of traffic. Work is slated to continue at the 4th St S and Main Avenue intersection until late-June. The intersection will reopen to north – south traffic movements when work is complete.

When traffic control is in place, drivers can expect:

  • Main Avenue between 2nd Street South through 4th St S intersection fully closed to traffic.
  • North side Main Avenue driveway access between 2nd Street South and 4th Street South will be maintained across Main Avenue into the Gateway Center parking lot by temporary roads.
  • Main Avenue pedestrian path will be maintained on the north side of Main Avenue between 2nd St S to cross at the temporary local access road and be carried on the south side of Main Avenue through the intersection closure at 4th St S.
  • Posted detour route is Northern Pacific (NP) Avenue between 8th St and 2nd St S.

Motorists should be aware of flood related closures affecting river crossing routes or adjacent downtown Fargo project work that may affect detour routes:

  • Opening Soon: 1st Avenue North bridge is expected to reopen at 4 p.m. today, April 25. The 12th Avenue bridge will reopen when the Red River reaches an elevation of 28 feet and debris can be removed.
  • Beginning Monday, April 29: City of Moorhead’s Center Avenue reconstruction work will begin with the utility work from 4 – 8 Street. Center Avenue bridge work is slated to begin soon after, which will require full closure of the bridge for six to eight weeks. Bridge traffic will be rerouted to 1st Avenue North. The bridge and utility projects are expected to be complete in mid-July.  
  • Complete in July: 2nd St S south of Main Avenue remains closed to all traffic for flood mitigation project work

Congestion is expected on the detour routes during peak hours of travel through downtown Fargo and into Moorhead. The NDDOT and City of Fargo urge motorists to not stop on railroad tracks and allow space between the vehicle ahead of you when congestion exists near railroad crossing on 8th Street South. Drivers are encouraged to plan ahead and think about the best routes based on your travel time through the area.
