The Montana Department of Transportation (MDT) and Robert Peccia & Associates (RPA) invite the public to attend an open house to learn more about recommended solutions from the US Highway 93 (US 93): Missoula to Florence Corridor Study. This study investigated the best possible improvements to increase safety, support efficient traffic operations, and accommodate area growth while minimizing impacts, constructability challenges, and costs.
The project team is inviting the public to stop by at any time during two in-person open houses to be held on Wednesday, January 22, and Thursday, January 23, from 4 to 7 p.m. at Lolo School, located at 5305 Farm Lane in Lolo, in the Commons.
At the events, recommended solutions will be available, including an optimized corridor configuration, intersection improvements, and potential locations for wildlife accommodations. Study experts will be on hand to answer questions. All are welcome to stop by at any time. No formal presentation will be made. The same information will be provided at both open houses.
Proposed recommendations will directly inform future roadway projects. However, no funding is currently secured. MDT and RPA are working in coordination with partners to identify potential funding sources, including grants, to move both short-term and long-term improvements along.
After considering public input at the open house meetings, MDT will issue the draft study report for public review in winter/spring 2025. The public review period for the draft report will be the final opportunity for public input on this study.
Anyone with questions about the study’s background, or who is unable to attend, please email Becca at

The Montana Department of Transportation (MDT) and its partners thank you for your ongoing feedback and participation as the US 93 Missoula to Florence study continues.
The study team anticipates initial findings for the Lolo to Florence Corridor will be available sometime this winter, in late 2023 or early 2024. Missoula to Lolo results will follow in approximately six months. Within this window, the study team will assess and recommend short-term and long-term measures to address needs along US Highway 93 (US 93), including specific intersections.
Separate from the Missoula to Florence study, a speed study was recently conducted between Missoula and Hamilton. Within this portion of the corridor, the speed study recommends maintaining the existing posted speed limits while adding a new 55-mph speed transition zone between the existing 65-mph speed limit and the 45-mph speed limit for northbound vehicles entering Missoula. In addition, the study recommends extending existing speed transition zones to half-a-mile in length and considering installation of traffic calming devices to encourage drivers to travel at posted speeds.
Though the Missoula to Hamilton speed study is complete, final approval has not yet been received. Following review by Missoula and Ravalli Counties and public comment, the Transportation Commission is anticipated to make its decision in a few months. Feedback submitted to the counties during this process will be considered. Our suggestion is to encourage community members to provide feedback to their county officials. We will communicate this to stakeholders interested in this US 93 study.
The Bitterroot Valley corridor is a priority for MDT. The study team recognizes the urgency for improvements.
