Project Vital Statistics as of November 17, 2021
Total Contract Work Completed: 88%
- Both the BNSF and OTVR railroad tracks are completed and operational.
- Approximately 70% of excavation has been completed (204,000 cubic yards). The remaining excavation is expected to be completed by approximately December 20.
- Approximately 87,000 feet of structural support piling (95% of total contract amount) has been installed.
- Concrete paving of SE Main Avenue near the Moorhead Youth Hockey Arena (MYHA) was completed to allow the second driveway access to the MYHA parking lot to be open after Thanksgiving.
Neighborhood Note: Night work (excavation and hauling of soil) will occur November 29-December 10.
Upcoming Milestones
- Complete remaining excavation; anticipated December 20, 2021
- No construction planned from approximately December 20 through early March 2022
- Complete underpass and open to traffic; anticipated June 2022
- Complete BNSF wye track and close 1 Ave S to through traffic; anticipated June 2022
Major Road Closure/Detour Continues:
Traffic should use either 1 Ave S, 12 Ave S, or Highway 10 as an east/west route and 34 St S or 8 St S as a north/south route. Closure of the intersection of SE Main and 20 St|21 St (all directions) will remain in place, likely until June 2022.
Other Travel Impacts:
20 St from 8 Ave to 6 Ave is now open, however, 20 St north of 6 Ave remains closed
21 St S from 2 Ave S to 4 Ave S and 4 Ave S from 21 St S to 22 St S is open to traffic, one lane in each direction
Main Ave from 17 St S to 19 St S and 19 St S from Main Ave to 4 Ave S is open to traffic
Project Description
The proposed project will reconstruct and realign the intersection of SE Main Ave and 20 St/21 St to pass under new bridges that will carry the BNSF and Otter Tail Valley Railroad tracks over the streets. The project will result in improvements to safety and congestion for vehicles, bicycles, pedestrians, and emergency services.
The project also includes the construction of new track (called a wye) that will allow direct northbound to eastbound and westbound to southbound train movements. Under existing conditions, trains must travel into the Downtown area, stop, and reverse direction to make these movements. The wye will eliminate delays at the Downtown crossings associated with trains backing up. Construction of the wye will require the closure of 1 Ave S near the wye track.
