A topping off ceremony at New England's soon-to-be third tallest residential building was held Tuesday morning in Boston.
To celebrate the milestone at "One Dalton Street," Boston Mayor Marty Walsh joined developers of the project and about 700 construction workers for the ceremony and a luncheon.
Once completed, the 61-story or 742-foot tower will house the Four Seasons Hotel and Private Residences, which will include 215 hotel rooms and 174 condominiums.
