The Massachusetts Bay Transportation Authority (MBTA) today announced its service updates which go into effect on Sunday, December 14.
Among these updates, 21 bus routes in total will increase frequency with 10 of those being upgraded to operate every 15 minutes or better. This is part of the larger Better Bus program aimed at improving the bus routes system wide.
Riders are strongly encouraged to check schedules in advance and to use the MBTA’s Trip Planner as well as the MBTA Go app to view live information.
Subway Updates
Orange Line: Trip time and reliability will improve due to operational improvements to reduce congestion at Oak Grove
Blue Line: Time between trips may shift by a few minutes midday between 12pm and 2pm to allow for maintenance and inspections. This will lead to improved reliability and predictability of passenger service.
Bus Service Improvements
Routes 32, 39, 57, 66, 71, 73, 77, SL1, SL3, SL5: These 10 routes will become Frequent Bus Routes with service every 15 minutes or better every day during most operating hours.
Route 64: To improve connectivity and consistency, weekend trips will no longer deviate to University Park in Cambridge, but will extend to Kendall/MIT seven days a week. University Park can still be reached by traveling to/from the bus at Central Square (inbound River Street, outbound Western Ave). Route frequency will also improve.
Routes 112 and 114: The bus stop located at the Chelsea Market Basket has moved from the east side of the store to the west side closer to the Carter St. side of the building due to building construction.
Route 7: Frequency will increase to alleviate crowding during AM and PM peak periods.
Routes 9, 21, 26, 45, 64, 69, 83, 116, 215, 225, 245: Frequency will increase.
