Montana Completed Projects and Studies
The Montana Transportation Commission and Montana Department of Transportation (MDT) use a transparent, data-driven asset management process to distribute limited funding to address highway improvement needs on Montana's major highways.
Based on overall policy goals and actions established through TranPlan 21, Montana's statewide transportation plan, the Performance Programming Process (P3) uses safety, congestion, bridge, and pavement data from MDT's management systems to help the Commission and MDT determine the most cost-effective distribution of Federal and State funding to highway systems and improvement categories. MDT's District Administrators then propose projects, based on public input, that conform to these overall funding distribution decisions.
The public has an additional opportunity to comment on proposed projects through the annual Statewide Transportation Improvement Program (STIP), a five-year list of projects. Finally, MDT adjusts the schedule of projects through the Tentative Construction Program (TCP) annually to reflect funding constraints or delays in project development.
MDT also uses information from its management systems and input from the public during the development of Corridor Planning Studies.

Types of Projects
What are the types of projects?
The annual Statewide Transportation Improvement Program (STIP) identifies proposed transportation capital and operating projects for the next five years. Highway project information includes project number, route and reference post, estimated completion year, and a general description of the proposed scope of work.
MDT's Tentative Construction Program (TCP), a project scheduling process, identifies the general location of highway construction projects planned within the next five years.
Corridor Planning Studies
MDT uses corridor planning studies to determine cost-effective ways to address corridor transportation needs. Corridor planning studies emphasize early and continuous involvement of the public and environmental, regulatory, and resource agencies. The studies generally contain the following elements: issue identification, documentation of existing conditions, environmental analysis, traffic forecasts, development of goals and a purpose and need statement, and a list of improvements to meet goals and long term corridor needs.
Traffic studies examine traffic volumes and patterns on a specific roadway or corridor.
Transportation Plans provide State, local, and tribal governments with a valuable way to determine and address future transportation needs in their jurisdictions based on public input and technical analysis.
