The MBA runs primarily in the San Juan metropolitan area. More specifically, there are thirty-nine routes including five express routes. Passengers are picked up at their homes and brought to any location that the MBA serves, but people must schedule their pickups in advance. The ferry service in San Juan is owned and operated by the port authority. Passengers can take a ferry from the tourist dock in San Juan to Fajardo, Vieques, Catano, Old San Juan and Mayaguez.
Some routes require passengers to be at the port one hour before departure.
This service only runs up and down the streets of Old San Juan. This line will link the central business district of the island to residential and employment areas in San Juan and surrounding communities. The train is scheduled to begin operating in November, 2001.
