All four lanes of Interstate 94 between Bismarck and Mandan are expected to be open and back to normal use by midweek, marking the end of the $11.4 million road construction project that began in the spring.
All construction work was anticipated to be completed by Tuesday, with lane striping and the removal of traffic control barriers to follow.
The 12-foot width restriction will remain in place until official completion of the project, and motorists are encouraged to obey all traffic controls and posted speed limits throughout the construction zone.
The construction project, consisting of concrete pavement repair, asphalt overlays and bridge work, spanned about 5 miles and involved all lanes of I-94 between Bismarck and Mandan, from just east of Exit 161 to the west side of the Grant Marsh Bridge.
The interstate remained open to east- and westbound traffic throughout the project, utilizing a combination of lane closures and head-to-head traffic, with speeds reduced to 45 mph or less throughout the corridor.
Ninety percent of the project was federally funded, with the remaining 10 percent covered by state funds.
