MBTA #0276 in Crosstown Bus branding on the CT2 line at Sullivan Square.

The Massachusetts Bay Transportation Authority operates three crosstown bus routes in the Boston, Massachusetts area, CT1, CT2 and CT3, intended as limited-stop buses connecting major points. All crosstown buses have bicycle racks and offer transfers to the subway at a cost of an additional 45 cents if a CharlieCard is used. They only run weekdays and are based out of the Albany Street garage.

The CT buses are envisioned as a first phase in a gradual improvement in circumferential service connecting the "spokes" of the Metro Boston rapid transit system, planned to culminate in the Urban Ring.



The CT1 (internally 701) runs between Central Square, Cambridge and the B.U. Medical Center/Boston Medical Center, mostly along Massachusetts Avenue. The majority of its route is a limited-stop version of the 1.

The CT3 (internally 708) connects the Longwood Medical Area to Andrew Square, all in Boston. The route roughly parallels the 8. The CT3 used to continue east to Logan Airport, but that part (internally 709) was dropped due to low ridership in March 2002. A few early morning trips were kept as the 171, running from Dudley to Logan.
