MDT schedules informational public open house to discuss US 191 Corridor Planning Study

GALLATIN COUNTY, MONTANA (January 14, 2020) The Montana Department of Transportation (MDT), in partnership with the Federal Highway Administration (FHWA), local jurisdictions, resource agencies, and the public, is developing a corridor study of US Highway 191 (US 191) in Gallatin County. The study will examine the highway between the intersection with Huffine Lane/Norris Road/Jackrabbit Lane in Four Corners (RP 81.9), and the intersection with Beaver Creek Road south of Big Sky (RP 45.3).


MDT recognizes the importance of this study to the communities along the corridor. An informational public open house is being held to provide information to interested parties about the scope and purpose of the study, collect feedback, and answer questions. To better serve the area, the open house will be held at two locations on two separate dates. The format and content of each open house will be the same. Please attend whichever day and location is most convenient for you. The open houses will be held at the following locations:


  • Gallatin Gateway Community Center

145 Mill Street (Gallatin Gateway, MT)

Tuesday, January 28, 2020; 3:00 PM to 6:30 PM


  • Warren Miller Performing Arts Center

45465 Gallatin Rd (Big Sky, MT)

Wednesday, January 29, 2020; 3:00 PM to 6:30 PM


The US Highway 191 Corridor Study is a pre-environmental study that allows for early planning-level coordination with the public, stakeholders, and environmental resource agencies. The goal of the study is to identify short- and long-term improvements to address safety, geometric and environmental concerns based on the needs presented. The study will help ensure an efficient transition from transportation planning to future project development/environmental review, if any, based on need and funding availability. This planning-level study is not a design or construction project.


The purpose of the meeting is to inform interested parties about the scope and purpose of the planning study, to solicit input on the existing conditions, and to understand roadway concerns within the study area that may be relevant to the planning effort.


Community input is a very important part of the process. Both the general public and the media are encouraged to stop by at any point to learn more about the study and speak with the team. The Montana Department of Transportation takes their mission to improve the safety of public roads seriously and values input from the community along with questions or concerns.


Comments and concerns may be submitted in writing at the meeting or by mail to Katie Potts, Montana Department of Transportation, PO Box 201001, Helena, MT 59620, or by email to
