(Bismarck, ND) — Lane shifts begin this week on I-94 as construction work on the Grant Marsh Bridge between Bismarck and Mandan continues. Drivers will use the outer-east and westbound lanes starting today, before traffic switches to the eastbound lanes on Wednesday. Crews have also removed the temporary ramp at westbound Exit 156, allowing drivers to use the old ramp. Workers are currently replacing the bridge’s concrete, building new approach slabs, and resetting guardrails that were removed.
