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.

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

Construction Impacts

During construction, two-lane, two-way traffic will be maintained throughout each work zone. During winter shut down periods, the interstate will reopen to four lanes total.


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.
