Best of Boston

This is the site to hit before you go anywhere. Updated every few minutes, SmarTraveler.com offers information about tie-ups on local roads and the MBTA. Even better than the concise written alerts are the live video feeds form problem-prone paces like the Central Artery, the Cape Cod bridges, and Route 128. The picture quality is good, though you can’t quite discern drivers’ obscene hand gestures as they back up on Storrow.
