Revise MDT and transportation commission roles in transit

This bill clarifies the division of responsibilities between Montana's Department of Transportation and the Transportation Commission regarding transit funding. It authorizes the Department to allocate federal transit and freight assistance funds for rail and transit projects, while allowing the Commission to transfer federal funds between highway and transit programs. Additionally, the bill permits the Commission to delegate its funding responsibilities to the Department. These changes aim to streamline how transportation funds are managed and distributed across different transit-related initiatives.
