BISMARCK, N.D. – Repairs and improvements to Grant Marsh Bridge on Interstate 94 are making great progress with a significant change to traffic control coming next week.
On Monday, July 8, traffic will begin using the outer eastbound and westbound lanes. Starting Wednesday, July 11, traffic will switch to head-to-head in the eastbound lanes.
Additionally, crews have removed the temporary ramp at westbound Exit 156, allowing traffic to continue onto Bismarck Expressway using the original loop ramp.
Crews have made structural improvements on the eastbound bridge, replaced the concrete on the bridge deck at the finger joints, constructed new approach slabs and reset the guardrail that was removed to allow for construction activity. The traffic changes allow crews to continue the project on the westbound structure.
The on-ramp for eastbound I-94 traffic from Bismarck Expressway will remain closed until the project is completed.
Speeds are reduced to 40 mph in work zones. Motorists are encouraged to use the zipper merge method to keep traffic moving. Merge points are set up just before the points of lane closures along I-94.
