Helena begins work toward a Montana Avenue railroad grade-separation project
The City of Helena has begun preliminary work toward a railroad grade-separation project on Montana Avenue, supported by a $3.2 million federal Railroad Crossing Elimination grant awarded in 2025.
In its June 3 announcement, the city said it is gathering and analyzing baseline project information. The announcement signals the start of early project work, not the start of construction.
The Montana Avenue Grade Separation project is a railroad grade-separation effort on a Helena corridor. The city has not released a final construction design, a total project cost, a construction start date or a completion date.
Grant funds early project advancement
Helena received the $3.2 million award through the federal Railroad Crossing Elimination program in 2025. The city is now advancing the project while collecting and reviewing the baseline information needed for the next stages of planning.
A grade-separation project concerns the conflict created when a street and railroad cross at the same level. The city’s available project information identifies Montana Avenue as the location for the effort, but does not specify the final form the project would take.
The information released with the project launch also does not identify how many railroad crossings or traffic lanes could be affected. It does not establish that the grant represents the full funding needed to build the project.
Why the project is being advanced
The project is intended to address a railroad-crossing conflict on a key Helena corridor. The city’s project description points to potential implications for traffic reliability, emergency response and crossing safety, though the available information does not quantify those potential effects.
For people who travel on Montana Avenue, the immediate change is the beginning of the city’s information-gathering and analysis process. No construction schedule has been announced, and the city has not said when drivers or nearby users could see physical changes along the corridor.
Public involvement expected later in 2026
Helena said community-involvement opportunities are expected to be announced later in 2026. The city did not provide dates, meeting formats or other details about those opportunities in its June 3 release.
The next known step is continued baseline work, followed by the city’s planned announcement of public-engagement opportunities. Residents, drivers and others interested in the Montana Avenue corridor will have more detail to assess as the city develops the project and outlines its community process.
For now, the confirmed milestones are the 2025 federal grant award, the June 2026 project launch announcement and the city’s ongoing baseline analysis. Key decisions about design, construction timing, total cost and the project’s physical scope remain unspecified in the available city information.
