The US 93: Missoula to Florence Corridor Study is a priority for the Montana Department of Transportation (MDT) and its partner Robert Peccia & Associates (RPA). The study team appreciates the comments, feedback and questions received. Your participation is highly valuable in determining solutions for the corridor.
MDT and RPA are determining both short-term and long-term safety improvements for the US Highway 93 (US 93) Missoula to Florence corridor. Based on public feedback gathered this past fall and winter, the project team will be using the next few months to evaluate solutions for US 93 and identify intersection and location-specific improvements to enhance safety for travelers. These improvements will also take into consideration the safe passage of our state’s diverse wildlife population.
Meanwhile, the project team is actively seeking funding, including grant opportunities, to support short-term improvement efforts.
Updates will be provided as the study progresses and public meetings are scheduled.
In addition, thank you again to last November’s virtual and in-person open house attendees. If you missed the events, you can view the recording of the virtual open house and display boards linked here.

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.

The Montana Department of Transportation (MDT) and Robert Peccia & Associates (RPA) are continuing on the US Highway 93 (US 93) - Missoula to Florence Corridor Study.
For those who may have missed the previous project update, MDT and RPA are including US 93 from Lolo to Missoula as part of this roadway study in response to public feedback received. Results from this additional study area will be included with information and proposed alternatives determined for the initial area from Lolo to Florence.
Environmental analysis began in the Missoula to Lolo area at the end of April. Traffic data collection will begin this summer, with follow-up data collection in the fall to capture operations near the new Lolo School.
The project team still anticipates initial study results (Lolo to Florence) to be available in late 2023 or early 2024. There will be a six-month extension for study results between Lolo and Missoula. MDT and RPA appreciate the feedback received from the public and local stakeholders, and hope to determine short-term and long-term solutions to enhance safety on US 93.
This Bitterroot Valley corridor is a priority for MDT, and this study is focused on identifying needed safety improvements. As existing funding is limited, MDT and RPA are working to seek supplementary funding to address safety concerns across the region, and for this US 93 corridor specifically. Please know that we recognize the urgency for improvements.
If you have additional information or feedback about the Missoula to Florence corridor, the team would love to hear from you.

The Montana Department of Transportation (MDT) and Robert Peccia & Associates (RPA) continue progressing on the US Highway 93 (US 93) - Lolo to Florence Corridor Study. MDT and RPA are now including US 93 from Lolo to the Missoula city limits as part of this roadway study in response to public feedback. Results from this additional study area will be included with information and proposed alternatives determined for the initial portion from Lolo to Florence.
Moving forward, MDT and RPA will conduct similar data collection and traffic analysis between Lolo and Missoula, extending to the Bitterroot River bridge at the Missoula city limits. The team will be working to facilitate meetings with all landowners, businesses, and stakeholders in the area who are interested in providing feedback. Multiple open house/public meetings will be held in 2023 to continue gathering feedback and presenting ideas and concepts for the Missoula to Florence corridor.
The second round of public and stakeholder meetings will be held in late summer or fall of 2023. The study team aims to provide and discuss the preliminary results at that time. Updates will be provided as this milestone approaches.
MDT and RPA appreciate the feedback received from stakeholders and hope to determine short-term and long-term solutions to increase safety on US 93. The study team still anticipates initial study results (Lolo to Florence) to be available toward the end of 2023. There will be a six-month extension for study results between Lolo and Missoula.
Roadway improvements are a large piece of the equation in enhancing safety and driver focus. Remember to buckle up, be mindful of drivers around you, and limit distractions when driving.

Progress continues on the US Highway 93 (US 93), Lolo to Florence Corridor Study being conducted by the Montana Department of Transportation (MDT) and Robert Peccia & Associates (RPA).
The virtual open house recording from October 18 is posted on the study webpage at this link if you missed the event or would like to review materials.
Crews have completed crash and traffic data collection, and the RPA team is now conducting traffic analysis. RPA is also partnering with Herrera Environmental Consultants to further evaluate wildlife and environmental considerations throughout the area.
In feedback received via email, social media, phone and during recent public meetings, many residents have identified that turning left onto US 93 from side streets and turning right off US 93 is a challenge for drivers. In addition, many residents have noted the speed limit as a concern. Center turns lanes, right turn lanes, and frontage roads have been suggested as possible future safety improvements.
The team has received this feedback repeatedly over the last few months and is working to address it. Other details and comments are also being considered as potential solutions are being identified. MDT and RPA are grateful for the participation and feedback received so far.
All comments received via email, phone and social media have been recorded and read by the study leadership team.
If you have additional information or feedback to share, the team would love to hear from you. Please email Becca at

The Montana Department of Transportation (MDT) and Robert Peccia & Associates (RPA) thank you for your interest and feedback thus far regarding the US 93, Lolo to Florence Corridor study.
The study has kicked off as of July 2022. Crew members have begun collecting crash and traffic data, conducting analysis, and taking field observations. In addition, an environmental evaluation is being completed. MDT and RPA recognize the challenges drivers, bicyclists, pedestrians, and wildlife face with growing traffic rates throughout the area and are working hard to gather real-time data.
MDT and RPA are grateful for your support and participation throughout the project. An open house will be held virtually and in-person in mid-October to provide an opportunity to chat with the project team and learn more about the study’s progress. More details on this will be provided as the date approaches.
As the study progresses, the team is interested in gathering qualitative feedback on US 93 between Lolo and Florence from surrounding businesses, landowners, residents and stakeholders.
All comments received via email, phone and social media thus far have been recorded and read by the project leadership team.
