What is a Corridor Planning Study?

MDT has developed a Corridor Planning Study process to provide a better link between early transportation planning and environmental compliance efforts. The Corridor Planning Study process involves conducting a planning-level evaluation of safety, operational, geometric, and environmental issues to identify needs and constraints within a corridor. This process allows MDT to save time and money in subsequent project phases by facilitating early identification of constraints within a corridor, development and screening of possible improvement options, and early coordination with community members and other interested parties.

A Corridor Planning Study is a planning document that considers multiple improvement options throughout a transportation corridor. This early planning process is distinct from the environmental compliance, design, and construction phases of an individual project.

What was the outcome of Phase I of the Badrock Canyon Corridor Planning Study?

Phase I entailed a public involvement effort to identify possible concerns along US 2 between Reference Post (RP) 140.0 and RP 142.4 (the intersection of US 2/6th Street West). MDT hosted an informational meeting on May 12, 2011 to determine if there was sufficient interest in moving forward with a Corridor Planning Study. Based on public feedback, MDT determined that there was local interest in pursuing further analysis of the corridor.

What did Phase II involve?

Phase II entailed preparation of a Corridor Planning Study. Phase II was initiated in September 2011 and was completed in September 2012.

Who conducted this study?

The Montana Department of Transportation conducted this planning effort. DOWL HKM assisted MDT in completing Phases I and II.

How was the public involved?

The public was invited to participate throughout the planning process. A total of three informational meetings were held during Phases I and II. Announcements of public involvement opportunities were sent to the study mailing list, published in local media, and posted to the study website.

Members of the public were also encouraged to review information posted on the study website and provide input throughout the study.

MDT and DOWL HKM collected and considered all public comments to better understand public views of potential issues in the corridor.
