Miami-Dade Transit (MDT) is the primary public transit authority of Miami, Florida and the greater Miami-Dade County area. It is the largest transit system in Florida and the 15th-largest transit system in the United States.[4] As of 2023, the system has 80,168,700 rides per year, or about 266,600 per weekday in the third quarter of 2024. MDT operates the Metrobus with their paratransit STS systems run by LSF. MDT also operates two rail transit systems: Metrorail and Metromover.
Metrobus operates over 93 routes, including the South-Dade Transitway.[5] MDT's main transit stations are Government Center in Downtown, and the Miami Intermodal Center in Grapeland Heights, which can access the Miami International Airport.[6]
Metrorail is composed of two rail lines (Green and Orange lines) with 23 stations radiating from the city center towards outlying neighborhoods north and south of Downtown. Metromover operates throughout the Downtown, Omni, and Brickell neighborhoods, and is composed of three rail loops and 22 stations. The opening of the Metrorail Orange Line in July 2012 significantly increased usage of the system.[7] As of 2013, rail fares collected were $23 million/yr and it cost $78 million/yr to operate the rail system.[8]
Tri-Rail is a separate entity and not controlled by MDT. Tri-Rail, a commuter rail system in the Miami metropolitan area, is directly connected at the Tri-Rail and Metrorail Transfer station, Miami Intermodal Center, and Government Center station.
