Beginning October 27, westbound traffic on Interstate 94 at Exit 161 in Bismarck will be redirected from a temporary exit ramp to a newly constructed ramp. This change marks the start of day and night construction work on the new I-94 west entrance loop.
Traffic control measures, including flagging operations, will guide drivers through areas where crews are working on curb and gutter installation as well as dirt and concrete paving. Drivers are advised to watch for trucks entering and exiting Centennial Road north of the bridge.
The east half of Miriam Avenue is close to completion and is expected to reopen by October 30, weather permitting. Once reopened, northbound traffic on Centennial Road/Bismarck Expressway will shift from southbound lanes onto new northbound lanes. Despite this shift, only one lane in each direction will be open, with left turn lanes available at intersections.
Motorists are encouraged to use caution when traveling through the construction zone and remain alert for workers and equipment.
The I-94 Exit 161 Interchange project began in spring 2024 and is scheduled for completion in summer 2026. The North Dakota Department of Transportation (NDDOT) stated that the project aims "to improve traffic flow by eliminating two left-turn movements and adding right-turn loops for more efficient travel." NDDOT expressed appreciation for public patience during ongoing work: "NDDOT appreciates the public’s patience and cooperation as this essential infrastructure project moves forward."
