2 Worcester Regional Transit Authority The WRTA is responsible for the provision of public transit services to thirty- five (35) communities within the Worcester County region, and is funded with federal, state and local monies, as well as fare box revenue. WRTA was created pursuant to Massachusetts General Laws, Chapter 161B, in August 1974. CMTM, a division of First Group, is WRTAs current Contractor for fixed- route service and demand response paratransit service management Services. The WRTA is the second largest RTA in Massachusetts serving the second largest city in New England
