T service interruptions planned for Sept. 19 and 20

The weekend approaches and with itt come construction-related delays and service changes on the T.

BLUE LINE: Starting Saturday, Sept. 19 into Sept. 20, all passengers will board and exit the westbound platform at Bowdoin.

ORANGE LINE: The Winter Resiliency Improvement Program is in full swing, meaning shuttles will replace service between Sullivan and Oak Squares on Sunday through Thursday. That means busses between Oak Grove, Malden Center, Wellington, Assembly and Sullivan Square. This pattern is expected to hold until October 15.

RED LINE: Construction crews will be working on the rails starting on Saturday through Sunday evening. That means shuttles will run between JFK/UMass, North Quincy, Wollaston, and Quincy Center.

GREEN LINE: No construction planned.
