The Montana Department of Transportation (MDT) construction project at the intersections of Underpass Avenue/State Avenue and 6th Street West/Central Avenue has begun. Riverside Contracting, Inc. has begun work to reconstruct the intersections to enhance traffic operations and safety in the south-central Billings area.

The project incorporates new traffic signals, storm drain, lighting, improved pedestrian facilities, and upgraded signage to improve these intersections, promote accessibility, and enhance safety features.

Work in-process:

* Water mains are being replaced

* The shared-use path is being constructed

* Retaining wall construction will begin next week

* Signals are being removed

Traffic advisories:

* 6th Street underpass between stop lights: While work occurs in the underpass, traffic is reduced to single-lane travel in each direction.

* Underpass Avenue south of State Avenue intersection: The Underpass Avenue/Calhoun Lane intersection is closed while the team replaces the water main under the street. This closure is expected to take a few weeks. Use Orchard Lane as an alternate route.

* Laurel Road west of Underpass Avenue and State Avenue east of Underpass Avenue: While the team replaces the water main under the street, traffic is reduced to single-lane travel in each direction.

* The signals are being removed on the southern intersection. Temporary signals will be used for the next couple of months while the new intersection is built.
