Autoridad Metropolitana de Autobuses was created as a public corporation on May 11, 1959. The operations would later be integrated into the Department of Transportation and Public Works in 1973 and the Integrated Transit Authority in 2014. It is the second oldest public transport authority in America, behind New York's Metropolitan Transportation Authority.

AMA is one of three major public transportation systems serving the San Juan metropolitan area, along with Tren Urbano and the Cataño Ferry. All system ridership combined is estimated at 80,000 people on work days.[2]
