Road construction to begin on Bismarck Expressway and I-94 to Mandan

Road construction on Bismarck Expressway and I-94 to Mandan will start next week. On Monday, April 1st, crews will begin roadwork on a two-mile segment of Bismarck Expressway from just east of Bismarck Expressway Bridge to I-94 west toward Mandan. Work will also start on a half-mile segment of I-94 Eastbound at Exit 156 (East Midway Interchange). Traffic lanes will be reduced by one lane in each direction and speed limits will be reduced, in addition to width and height restrictions in some areas. Electronic signs alerting travelers to the work have been put in place in a continual effort to ensure the community and surrounding areas are aware of the project.

This is the first phase of a multi-phased project taking place this year. The road construction work will be conducted in phases in an effort to reduce impact to motorists. Next week work consists of installing a bridge canopy for bridge deck replacement on the I-94 overhead bridge near the I-94 Eastbound Exit 156. It will also include bridge work near McKenzie Drive Exit and Memorial Highway Exit on Bismarck Expressway.

During construction:

  • Traffic lanes will be reduced one lane in each direction.
  • Speeds will be reduced to 45 mph.
  • Flaggers may be present at immediate work zones. Motorists should expect delays.
  • 11 foot width restrictions will be in place near McKenzie Drive, Memorial Highway and Eastbound I-94 (Exit 156)
  • A height restriction of 15’ 6” will be in place on Eastbound 1-94 (Exit 156).

During the construction season, the overall project will work on 13 miles of roadway on Interstate 94 East and West bound from Exit 147 (Hwy 25) west of Mandan to the Grant Marsh Bridge, including work on Bismarck Expressway from Washington Street in Bismarck west to Interstate 94. Project work consists of concrete pavement repair, asphalt overlays and bridge work on several bridges.

The North Dakota Department of Transportation (NDDOT) encourages local motorists, which include businesses and commuters, to plan ahead during the upcoming construction season. I-94 and Bismarck Expressway will be open to traffic at all times throughout this process, utilizing a combination of lane closures and head-to-head traffic. Width restrictions will be in place and the speed limit will be reduced to 45 mph or lower at times throughout the construction zone.

Construction work is expected to be completed in late fall. Regular updates on construction progress will be provided to the public throughout the construction project.
