Billings Bypass yellowstone river bridge

Project Overview

The Billings Bypass project is a multi-phase project that will result in a new arterial roadway. The new road will begin at the Johnson Lane Interchange on Interstate 90 (I 90) in Lockwood, Montana, span the Yellowstone River, and connect to the Highway 312/US Highway 87 (US 87) intersection in the Billings Heights. An additional segment reconstructed Five Mile Road, north of the new road, and now connects Five Mile Road to Old Highway 312.
