Construction of the deck over the heavily traveled section of Interstate 90 known as the Massachusetts Turnpike between Beacon Street and Brookline Avenue will be the largest air rights structure built in Boston since Copley Place in 1980, the release said, and will take approximately 24 months to complete.
The deck construction phase will require closures of a single east and west bound travel lane and additional late night lane closures to accommodate the construction of the deck and building foundations.
