About
 
The Maryland 511 Web site is part of a statewide travel information service which provides reliable traffic and weather information to travelers to reduce congestion, and improve safety and mobility in Maryland.

Using real-time traffic data from various sources throughout the state, we are able to provide current information to commuters, travelers and commercial carriers so they can make informed decisions regarding their next drive to work, trip or delivery. By providing this information to travelers, 511 Maryland helps to keep traffic moving.

Key features of the site includes:
  • An interactive map enabling site visitors to view traffic conditions statewide or to focus on a particular region.
  • Links to the various transportation service providers throughout Maryland.
  • Breaking traffic news via an alert scroll panel.
In addition to this Web site, the 511 telephone service provides travelers with real-time traffic conditions anywhere they have access to a phone. This free service can be accessed from most locations in the state. If you are unable to reach 511 Maryland, your telephone carrier may not yet support this new service. Callers can still access Maryland 511 by dialing 855-466-3511 (855-GO MD 511).
