I90 Yellowstone River Bridge in March 2022

Project Overview

The Montana Department of Transportation will widen and reconstruct Interstate 90 in Billings between the North 27th Street Interchange and the Lockwood Interchange from two lanes to three. The project also includes reconstruction of the bridges over the Yellowstone River and the Talen Energy railroad spur line. Improvements are designed to meet safety, traffic operations and capacity needs in the future. Other project features include two irrigation crossings, lighting, signage, and on/off ramp upgrades.

Project Construction

Construction is scheduled to begin in fall 2021 and will be completed in phases, and includes winter shutdown periods. The entire project is tentatively scheduled to be complete in 2024.

During Construction

Work hours will primarily occur between 6:00 am and 10:00 pm. Night work will be advertised in advance and will be limited.

Traffic shift! Traffic will be shifted down to one lane each direction to accommodate construction. Two-way traffic will be maintained throughout the work zones. During winter shutdown periods, the interstate will be reopened to four lanes total.

Speed limits between 15 and 55 mph will be posted in construction zones. Please pay attention to changing speed limits for the safety of our workers!

Temporary ramp closures will be used to safeguard workers and the traveling public. These will be limited and advertised in advance.

Montana's roads and bridges are mainly funded through a combination of federal (88.5%) and state/local (11.5%) funding sources. MDT receives no funding from Montana's general fund revenue. Federal road and bridge revenues are generated from the users of our highways through gasoline and diesel fuel taxes and apportioned to states through federal highway legislation.
