Maryland Transit Administration

The Maryland Transit Administration (MTA) is a state-operated mass transit administration in Maryland, and is part of the Maryland Department of Transportation (MDOT). The MTA operates a comprehensive transit system throughout the Washington-Baltimore metropolitan area. There are 80 bus lines serving the Baltimore Metropolitan Area, along with rail services that include the Baltimore Light RailLink, Baltimore Metro Subway, and MARC Train. In 2025, the system had a ridership of 67,092,400, or about 190,300 per weekday as of the first quarter of 2026.

With 27% of Baltimore households lacking access to a car, the MTA is an important part of the regional transit picture. The system has many connections to other transit agencies of Central Maryland, Washington, D.C., Northern Virginia, and south-central Pennsylvania (Hanover, Harrisburg, and York): WMATA, Charm City Circulator, Regional Transportation Agency of Central Maryland, Annapolis Transit, Rabbit Transit, Ride-On, and TransIT.
