On Wednesday, May 16th, MassDOT will be paving the southbound lanes at the Cradock Street Bridge (Main Street, Medford Square). Only one southbound lane at a time will be open in the section of Main St. between High St and the Route 16 westbound. Expect traffic delays and take alternate routes if possible. We appreciate your patience. Thank you.
