Public Transportation & Aeronautics Programs

MDOT’s Public Transportation (rail, bus, public transit, marine) and Aeronautics programs are administered by three separate offices: The Office of Passenger Transportation (OPT) manages bus and marine programs, the Office of Rail manages rail and port programs, and the Office of Aeronautics administers the aviation program. These offices provide capital and operating assistance, technical support, and safety oversight for the department’s Public Transportation and Aviation Programs.

MDOT’s approach to the Public Transportation and Aviation Programs differs from the Highway Program in that much of the infrastructure is owned, managed and operated by entities other than MDOT, and the funding that MDOT is responsible for represents only a small portion of the overall investments in these modes.

MDOT’s 2024-2028 Public Transportation (rail, bus, public transit, marine) and Aeronautics programs are estimated at $4.7 billion, with $3.7 billion in Public Transportation covering $2.9 billion in Bus and Marine, $801 million in Rail, and $989 million in Aeronautics investments. These investments will provide essential support for developing and maintaining a vibrant and sustainable multimodal transportation system that provides safe and easy movement of people and goods throughout the state.
