The Johnson Lane interchange will be Montana’s first diverging diamond interchange, an intersection style that offers many safety benefits. A video simulating traffic flow through Johnson Lane Interchange is available here.

This project segment will also include work on adjacent streets and intersections to improve the operation of the interchange. These will include:

  • Johnson Lane.
  • North Frontage Road.
  • Old Hardin Road.
  • Cole Street.
  • Becraft Lane.

Construction Manager/General Contractor (CM/GC) is the project delivery method for this segment, which means that a contractor is engaged during the design phase to provide constructability reviews. In this role, they work closely with the owner (MDT) and design engineer (DOWL) to streamline project delivery. Granite Construction and LHC Inc. is the team that has been selected as the contractor for this segment.
