Objections rise over tower plan

Neighbors say 47-floor residential building would clog traffic, darken Copley Square

A proposal to build Boston’s tallest residential building in the Back Bay is generating objections from neighbors and public officials, who argue the project would worsen traffic problems, darken Copley Square with shadows, and skimp on public art and affordable housing.

Several groups have written to the Boston Redevelopment Authority in recent days to say those issues must be addressed before Simon Property Group can move forward with its plan for a 47-story tower at Copley Place.
