Mass511 is the official traffic & traveler app for Massachusetts commuters and travelers. Published by the Massachusetts Department of Transportation (MassDOT), Mass511 delivers reliable real-time road and travel information, covering interstates, U.S. routes, and state highways. Unlike other traditional map applications, Mass511 draws from live traffic and incident data from MassDOT Highway Operations Center. And that means you’ll know what’s going on as it happens.

With Mass511 you can:
- Get the latest on roadwork, construction, crashes, and other traffic incidents with our easy-to-use zoomable and scrollable map
- Check out real-time traffic and winter-weather conditions on our live camera feeds
- Save your commuting route and get traffic alerts tailored to you
- Compare up to three different routes for traffic conditions and delays
- Plan your trip by car
- Get notified about alternate routes as they become available
- Use Drive Mode to get hands-free audio alerts while on the road
