Construction to begin soon on Interstate 90 between Manhattan and Livingston

The Montana Department of Transportation (MDT) will begin construction soon on two projects to improve Interstate 90 between Manhattan and Livingston. The projects will improve safety, provide a smoother driving surface, and extend the life of the roadway for many years through this important corridor.

 The I 90 Manhattan to Belgrade Project will rehabilitate the pavement and upgrade guardrail from the Manhattan Interchange (Exit 288) to about three miles east of the Belgrade Interchange (Exit 299). Construction is anticipated to start this week.  

 Work will begin first on the westbound lanes. What to expect during construction:

 • Traffic will be reduced to one lane in the westbound lanes.

 • Eastbound traffic will remain two lanes.

 • Speed limits will be reduced through the work zone.

 • Wide loads will be staged and piloted through the work zone Monday – Friday.

 • 12-foot lane restrictions will be in place from 6 a.m. to 10 p.m.

 • 14-foot lane restrictions will be in place from 10 p.m. to 6 a.m.

 MDT anticipates work to begin on a second project in late May to upgrade and install new guardrail over the Bozeman Hill Pass. The project begins east of the Bozeman Trail Road Interchange (Exit 313) and ends about two miles east of the Flynn Creek Road Interchange (Exit 324). 

 Construction of both of the projects is expected to be completed in the fall 2021.

 “These projects will help ensure the roadway remains safe and will prolong the life of the road for years to come,” said MDT Engineering Project Manager Craig Walker. “For the safety of workers and other motorists, please pay attention to posted signage and slow down through the work zones.”
