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 in Lockwood, Montana, span the Yellowstone River, and connect to the Highway 312/Highway 87 intersection in the Heights neighborhood of Billings. An additional segment will reconstruct Five Mile Road north of the new road and will connect 5 Mile Road to Highway 312.

This project is led by the Montana Department in cooperation with the Federal Highway Administration (FHWA), Yellowstone County, and City of Billings. DOWL is the lead project engineer and public information coordinator and Morrison-Maierle is the lead bridge engineer. Kittelson and Associates along with Marvin and Associates are performing the traffic engineering and operational analyses.
