Massachusetts lawmakers delayed a vote to relax a 20-year-old state law restricting tall buildings from casting shadows on the Boston Common and Public Garden.

The Massachusetts Secretary of State has asked for a two-week delay on a vote that would change state law regarding shadows created by tall buildings. 

The Boston City Council recently approved Mayor Marty Walsh’s home rule petition to ease a 20-year-old state law that restricts shadows from construction on the Boston Common and the Public Garden to allow for construction of the 775-ft Winthrop Square tower proposed by Millennium Partners.
