Lockwood Interchange Reconstruction



Project Overview

The Montana Department of Transportation (MDT) is evaluating interchange and interstate improvements for the Lockwood Interchange and I90 in Billings. This includes the design of a Diverging Diamond Interchange. The project will also include widening I90 to three lanes in each direction between the Lockwood Interchange and the Johnson Lane Interchange.

The design phase of the project will occur from 2020 through 2023, with construction anticipated in 2024.


MDT will be working closely with community stakeholders, local business owners, and the general public throughout the design and construction process.
