Traffic Control Update
The 6th Street West underpass and both intersections north and south of the underpass have reopened to traffic. Riverside Contracting Inc. will return later this summer, after the chip seal has fully cured, to apply permanent pavement markings to the roadway. Expect single-lane closures and reduced speeds while this work is occurring.
Project Overview
Construction on the Underpass Avenue - Billings project began in the spring of 2023 and will continue through summer of 2024, weather and other factors permitting. The Montana Department of Transportation (MDT) partnered with Riverside Contracting Inc. to reconstruct the Underpass Avenue with State Avenue intersection, and the 6th Street West with Central Avenue intersection. The project will improve traffic operations in the south-central Billings area by incorporating new traffic signals, a new storm drain, lighting upgrades, improved pedestrian facilities, and upgraded signage.
