Meetings on Lockwood interchange project to be held Montana Department of Transportation and last updated 2021-03-11 18:50:24-05 Drivers will be seeing a lot of orange cones on 1-90 in Yellowstone County over the next few years as the Montana Department Transportation takes on some major projects with a goal of increasing capacity and safety through the much-traveled corridor. MDT will hold two virtual live informational meetings to share details about the Lockwood Interchange Reconstruction Project and answer questions and concerns. Plans call for making the Lockwood Interchange into what is known as a âDiverging Diamond Interchangeâ and to widen 1-90 to three lanes in each direction from there to the Johnson Lane Interchange.
