 CMRT was founded as the Corridor Transportation Corporation in May 1987 by the Baltimore Washington Corridor Chamber, and began its transit operation as Connect-a-Ride two years later with nine buses serving five routes.The non-profit organization gained independence and changed its name in the early 2010 timeframe, and the bus service rebranded to the same name in early 2013.In 2014, Howard County initiated its own Regional Transportation Agency of Central Maryland, recruiting Anne Arundel County to join.
