MDT launched the US 2 / MT 16 TRED Study in January 2006 to examine whether four-lane highway improvements to the Montana segment of the Theodore Roosevelt Expressway are justified by economic, safety, regulatory, and other considerations. The study was completed April 2007.

The MDT found that a divided four lane highway system would be the best option to provide system continuity with the Theodore Roosevelt Expressway, improve travel conditions, support economic growth, increase safety, and address current roadway design deficiencies.
