BISMARCK, N.D. – The North Dakota Department of Transportation will begin directing traffic through the two temporary loop ramps the week of May 5 as part of the Interstate 94 (Exit 161) Interchange Project.
This marks a major change in how drivers enter and exit I-94 at Centennial Road and Bismarck Expressway. These temporary loops will be in use until early fall 2025.
Upcoming changes to traffic flow:
- Drivers on Centennial Road/Bismarck Expressway will begin using the temporary loop on-ramp to enter I-94 West. The existing I-94 West on-ramp will be closed for reconstruction.
- Drivers on I-94 East will begin using the temporary loop off-ramp to access Centennial Road/Bismarck Expressway. The existing I-94 East off-ramp will be closed for reconstruction.
- Drivers entering I-94 East or exiting from I-94 West will use existing ramps.
To help prepare for these changes, NDDOT encourages drivers to visit dot.nd.gov/exit161 for the latest traffic pattern updates and to stay informed about ongoing construction.
The I-94 Exit 161 Interchange project began in spring 2024 and will continue through summer 2026. This redesign aims to improve traffic flow by eliminating two left-turn movements and adding loops for more efficient right turns. The NDDOT appreciates the public’s patience as this essential infrastructure project moves forward.
