Summer 2023 Service Changes

Route 111 Bus in a roundabout in Chelsea, during summertime

This summer, we're revising bus service schedules to better reflect service that will operate. Last season, MBTA bus service schedules did not always reflect bus arrival times due to operator shortages and not enough drivers to run routes daily. These changes in scheduled service will allow us to improve service delivery by decreasing long gaps/trip cancellations. Most subway lines will also experience service changes.
