Expect traffic delays I-90 rehab project in Mineral County begins April 1

The Montana Department of Transportation is rehabilitating I-90 between St. Regis and Superior. The project begins 1 1/2 miles east of St. Regis and ends approximately five miles west of Superior near the Dry Creek Road Interchange (Exit 43).

The project will resurface nine miles of concrete pavement, repair shoulders, and repave the Sloway Road Interchange ramps (Exit 37). The work is expected to begin April 1 and be completed in summer 2020.

During construction:

- I-90 traffic will be reduced to one lane in each direction.

- Both east- and westbound traffic will travel on the same side of I-90.

- Crossover traffic patterns will be in place throughout construction.

- Speed limits will be reduced in the construction zone for the safety of the traveling public.

“Interstate 90 is an important transportation corridor for local communities, the state, as well as the nation” said MDT Project Manager John Benda. “This project will improve roadway conditions and extend the life of the pavement by 10-15 years.”

The project includes a proven construction technique called a “Dowel Bar Retrofit” which will insert metal rods into the concrete pavement at the paving joints. The steel bars add strength and durability to extend the life of the pavement. Once the dowel bar work is completed, the surface of the concrete will be milled smooth to improve the ride. Dowel bar retrofits have been used successfully throughout the country.
