Phase MI-1 4th Avenue Currently In Construction

-- UPDATE --

June 19, 2020

Minot, N.D. – The construction contractor for Phase 1 flood protection in Minot is planning a 21 to 28-day closure of Third Avenue, just to the west of Broadway. Park Construction is scheduled to close a one block stretch of Third Avenue NW between Fourth Street NW and Broadway, starting Monday, June 22 (weather dependent). A detour route will be clearly marked that includes using Sixth Street NW and Fifth Avenue NW to get around the temporary closure.


“The contractor needs to remove the temporary storm sewer bypass pipe that crosses 3rd Ave NW that allowed for the construction of the Broadway Pump Station. The contractor will also be removing the temporary pavement that was installed over the bypass and replace with permanent pavement during this closure.  This work will require them to close this stretch of road for up to July 14th, 2020,” said Dan Jonasson, Director Souris River Joint Board. “We appreciate the patience of the driving public during this time while taking the detour in this area.”


This road closure will not impact the intersection of Broadway and Third/Fourth Avenue as the through traffic will continue in both north and south directions on Broadway.


The Phase MI-1 Fourth Avenue enhanced flood protection project is a six block stretch of levees, floodwalls, a new sanitary lift station, and a major storm water pump station from just west of Broadway to the east side of Third Street NE. Construction on this phase is scheduled to be complete in late 2020.

COVID 19 Update: During this uncertain time, the Souris River Joint Board wants to assure Mouse River Basin residents that we are as committed as ever to the continued design, construction and completion of the Mouse River Enhanced Flood Protection Project. As the construction season gears up, recommendations from the ND Department of Health and other state/federal regulatory agencies are being followed by contractors working on the three active construction projects (MI-1 4th Avenue Floodwalls, MI-2 Napa Valley, and MI-3 Forest Road) within the City of Minot. These efforts are being undertaken to protect construction crews and community members from contracting and spreading COVID-19. Construction work will continue as long as restrictions are not placed on the construction industry. We have been notified that there may be a delay related to some of the building materials and we will work through those issues as they present themselves by adjusting schedules and planning around those delays. It is also possible that due to the current world-wide impacts of the pandemic, the projects could experience completion delays, but the projects will be completed. Given the economic impacts of COVID-19, we want to remind you that funding has already been secured for the completion of these three projects. Finally, and most importantly, we care about our fellow residents and want to encourage you and your families to remain diligent by following the NDDOH and other agency recommendations to keep you safe.

Construction completion on this phase is slated for early 2021.
