 On the pike, you're down to one lane at a crawl. Westbound Tremont Street to Beacon Street. Eastbound Comm Ave through the Prudential Tunnel. The Copley Square off-ramp is closed. You're off at South Station instead. Sturrow Drive east of Tunnel to 93 North is closed with a detour. That detour clogging things up on Nashua Street by the Garden.
