BOSTON (AP) — Boston's plans to build the city's first new school building in more than a decade have hit a roadblock put up by the Massachusetts Historic Commission.

The commission is formally asking the city to find a different site in order to stave off demolition of the 102-year-old Dearborn school in Roxbury.

The Boston Globe (http://bit.ly/1KzUIS5 ) reports that Brona Simon, the commission's executive director, wrote in a letter to school officials that building a new school would have an "adverse effect on the historic Dearborn school building through the destruction of an historic property."

The Dearborn's original building opened in 1912 as the city's first public vocational school for girls.

Mayor Martin Walsh previously said that demolition is the only option because renovating the existing building is too expensive.
