Overnight maintenance on the G train this week will disrupt service south of Bedford-Stuyvesant.

The G trains will stop running between the Bedford-Nostrand avenues and Church Avenue stations from 10 p.m. to 5 a.m., starting Monday night through Friday morning.

The MTA will run shuttle buses for G train stops from the Bedford-Nostrand avenues station to Jay Street-Metrotech, where riders can catch the F train to reach affected G train stations between Bergen Street and Church Avenue.
