Subway riders who board at Wollaston Station in Quincy will be able to use that station through October, and possibly longer, before it closes for reconstruction.
The Massachusetts Bay Transportation Authority does not expect Wollaston to be closed before November, spokeswoman Lisa Battiston said.
The MBTA in April announced plans to close the station for 20 months, saying that would happen sometime in the fall. Battiston said the date and duration would be confirmed before the end of September, when the authority reviews the contractor’s baseline schedule.
Wollaston Station, on Newport Avenue, is part of the Red Line’s Braintree branch. During construction, trains will run through the station but will not stop there.
Buses will run between the Wollaston and North Quincy stations for passengers who walk or drive to Wollaston, and most of Wollaston’s parking spaces will be available during construction.
MBTA officials said they are revamping Wollaston Station at a cost of $38 million to make it accessible to all riders and to address chronic flooding problems. The full station upgrade will last through 2020; the station will be closed for 20 months but construction will continue for 35 months, officials have said.
The T will also start construction in the next few months at Quincy Center Station, also on the Braintree branch of the Red Line.
Most of the parking garage at Quincy Center will be torn down, the elevator will be replaced, and an accessible entrance at Burgin Parkway will be constructed.
The work won’t close the station, but the elevator will be out of service for 20 weeks. The dates will be confirmed before the end of September, Battiston said.
In June, the MBTA announced it had awarded a contract for $67.9 million for work at both Wollaston and Quincy Center stations.
