Improvements are proposed for Interstate 94 from the North Dakota Highway 25 Interchange to the Grant Marsh Bridge, as well as West Bismarck Expressway from the I-94 Interchange to the South Washington Street intersection.

The $11 million project is tentatively scheduled for the 2019 construction season.

“It could get pushed back, depending on funding,” said Chad Frisinger, design division transportation engineer with the North Dakota Department of Transportation.

The proposed improvements will include concrete pavement repair, mill and hot mix asphalt overlay, slurry seals, bridge deck overlays, bridge deck replacements and the installation of a permanent traffic signal system at the Sunset Drive Interchange.

The purpose of the project, according to the NDDOT, is to extend the life of the existing pavement in the areas outlined.

“It’s routine maintenance,” said Frisinger, noting these sections were last paved in 2006 and 2010.

He said the most-challenging and time-consuming part of the project will be the bridge deck replacement on the East Midway Interchange.

“The bridge repairs will cause the project to last all summer,” Frisinger said. “The overlay should be quicker, and take only about a month to complete.”

During construction, traffic will be maintained on I-94, although temporary closures of ramps and loop ramps may be required for the mill and overlay operations. Signage will be used to update motorists of delays.

Additionally, nighttime paving may be used for high-traffic areas of the project.

“The general traveling public can expect some delays,” Frosinger said, noting that vehicles with loads wider than 14 feet may need to take alternate routes.

The local cost share on the project is 10 percent, or approximately $79,000 and $35,000 for Bismarck and Mandan, respectively.
