Wollaston station on the MBTA’s Red Line will close for 20 months beginning in late December, not this fall, as the transit authority announced in April.
The station is closing for a $33.4 million renovation, which will make it accessible to all riders and address flooding problems. During the closure, trains will pass through Wollaston, but will not stop there, so the more than 4,600 passengers who board there daily must do so elsewhere.
The MBTA said it will run free buses between Wollaston and North Quincy, a distance of about a mile, while Wollaston is closed. The majority of parking spaces at Wollaston will remain open during construction.
The work will overlap with construction projects at other stations in Quincy.
At Quincy Center station, the T is spending $13.3 million to demolish the top three levels of the shuttered parking garage and is adding an accessible entrance on Burgin Parkway. Work there is expected to begin in late 2017 or in the first few weeks of 2018, said MBTA spokeswoman Lisa Battiston.
The station will remain open during the work, but the elevator there will be replaced and will be out for 20 weeks from June 1 until Oct. 18, 2018, Battiston said.
The garage demolition is intended to help the efforts of the T and the city in encouraging private development at the station, where the agency is soliciting bids from developers interested in the air rights above the facility.
The Wollaston and Quincy Center projects are on the same contract, which totals $67.9 million and includes funding for busing and a police traffic detail at Neponset Circle during the Wollaston closure.
MBTA officials informed the agency’s fiscal control board this month of their new timeline. Battiston said the timeline allows for the contractor to “fine-tune the project execution” and will not result in a delayed opening of the renovated station.Jill Terreri Ramos can be reached at email@example.com.
