Route 91 AMA: Bayamón Station – Santa Juanita
Route 91 connects Bayamón Station on the Tren Urbano with Avenida Santa Juanita, calling at the UPR Bayamón campus. It has a feature that is unusual in the network: the outbound and return trips do not follow the same itinerary.
Route: note that the return is different
Route 91 is one of the few in the network where the return trip does not retrace the outbound one. It is worth checking both itineraries before deciding where to wait for the bus.
