After a brief pause to reallocate resources, the Targhee Turn Lanes US Highway 20 (US 20) project is moving forward. The Montana Department of Transportation (MDT) has hired consultant design engineering firm Robert Peccia & Associates (RPA), Helena, to conduct the design phase of the project.
The project is still in the early stages of this phase and is progressing toward developing a scope of work, which is an outline of the final design and construction activities required to complete the project. A timeline for the project has not yet been determined.
