Next Main Avenue roadway construction phase begins on Thursday


Starting this week, the North Dakota Department of Transportation (NDDOT) and the City of Fargo contractors will be making traffic control changes within the Main Avenue Makeover improvement project in downtown Fargo.

Beginning Tuesday, May 5 at 7 a.m., crews working in the University Drive and Main Avenue intersection will detour southbound University Drive traffic heading westbound onto Main Avenue to allow room for necessary work in the center of the roadway. Traffic will be detoured to 1st Avenue South for approximately one week.

When traffic control is in place, motorists can expect:

  • Two southbound through lanes on University Drive
  • Single westbound right-turn lane on University Drive detoured to 1st Avenue South

After 7 a.m. on Thursday, May 7, the third traffic shift will begin between west of Broadway and east of 8th Street South with both intersections remaining open. As project work progresses and the University Drive intersection reopens in the next few weeks, crews will fully close the Main Avenue and 8th Street South intersection for up to two months. Business access and pedestrian traffic will be maintained.

When traffic control is in place, motorists can expect:

  • Main Avenue will be closed to traffic between west of Broadway and east of 8th Street South
    • Broadway and 8th Street intersections will remain open
    • 7th Avenue intersection will be closed to traffic
  • Speeds are reduced to 25 mph where traffic control is present

Main Avenue remains closed to traffic between east of University Drive to west of 10th Street South Underpass bridge.

Local access is maintained to all the north side businesses located in the project zone by use of 1st Avenue South to adjacent side streets. Motorists can then cross north or south over Main Avenue via:

  • 10th Street South (underpass frontage road, near the old McDonald’s)
  • 11th Street South, 12th Street South, or 8th Street South

Crews are planning to work west to east toward Broadway. The contractor can work on the project phases concurrently with restrictions on days for intersection work. Over the next weeks, motorists should expect additional reduced lanes or full roadway closures of Main Avenue as they move into the next phases of project work. The traffic impacts for the phase work will include:

  • Main Avenue between 10th Street and 8th Street (fourth traffic impact): The remaining roadway of Main Avenue will be reconstructed west of 8th Street South intersection.
  • 10th Street South Underpass Bridge (last traffic impact): The steel bridge deck under Main Avenue for the 10th Street South underpass will be replaced. There will be short-term lane closures on 10th Street South.

Drivers should plan to use the posted detour route to cross the Red River into Moorhead until project work is complete in mid-October. The posted detour route north of Main Avenue is 1st Avenue North and south of Main Avenue is 1st Avenue South between University Drive to 2nd Street South.

Pedestrian access to all businesses along Main Avenue is provided. The NDDOT and the City of Fargo urges motorists to always be attentive, drive with caution and never enter a road blocked with barriers or cones stating, “road closed.”


The two-year makeover of Main Avenue in downtown Fargo is a joint project between the NDDOT and City of Fargo to transform this gateway into a safe, accessible and beautiful passageway to and through the heart of Fargo.

In 2020, the final year of reconstruction work in the downtown area will improve Main Avenue between west of Broadway to east of University Drive, including the addition of a counterflow lane for northbound driving lane on University Drive to detour traffic between Main Avenue and NP Avenue. This lane will remain once construction is complete to add another northbound railroad underpass access into downtown.

Last year crews completed the first year of improvements ahead of schedule that improved the roadway, pedestrian facilities and upgrade the underground infrastructure between the Red River to Broadway, including the construction of a two-lane roundabout at 2nd Street South intersection.

When the roadway is complete this fall, Main Avenue roadway will be a hybrid design consisting of a:

  • 3-lane alternative from 2nd Street to 9th Street South, as well as double-lane roundabout at the Main Avenue and 2nd Street South intersection
  • 4-lane section between 9th Street South and 11th Street South
  • 5-lane section west of 11th Street

The cost of construction is estimated to be $11.5 million for 2020 project work, totaling about $23 million in improvements over the two-year project. Funding for the project will consist of a combination of federal, state and local assessments.

Constructed in the 1950s, this full stretch of Main Avenue is one of the oldest roads in Fargo. The project will improve 50 – 60-year-old underground infrastructure, an aging driving surface and lessen the pedestrian system gaps through the downtown corridor. The 2019 – 2020 project work from the Red River to University Drive includes:

  • Upgrade existing water main, sanitary sewer system and storm sewer
  • Construction of two-lane roundabout at the 2nd Street intersection
  • Replace roadway pavement, traffic signals, street lighting and landscaping features
  • Widen pedestrian facilities on both sides of Main Avenue, with new pedestrian crossings
  • Additional on-street parking
  • Addition of a counterflow lane creating a northbound driving lane on University Drive to detour traffic between Main Avenue and NP Avenue

During the design phase in October 2018, and after receiving feedback from property owners, the NDDOT and City of Fargo split the scope of work into two separate projects.

Fargo Main Avenue (US Highway 10) is part of the NDDOT Regional Highway System and serves as an arterial connection between Moorhead, Fargo and West Fargo.
