Boston Mayor Thomas M. Menino today released plans to make City Hall and the surrounding plaza more accessible for people with disabilities. Construction is slated to start this spring for a new ramp that will allow disabled people to more easily access the front door of City Hall, according to a statement by Menino’s office. For those who struggle traveling on the brick surface of the plaza, the plans also include a smooth concrete path from Court Street to the City Hall entrance. “Everyone is welcome, and everyone should feel comfortable getting around in City Hall Plaza,” Menino said today in a statement.
