Q. Road Condition and Closure Information
The Federal Highway Administration (FHWA) National Traffic and Road Closure Information web site is the best place to start for road conditions across the nation: http://www.fhwa.dot.gov/trafficinfo/index.htm
In some areas you can also get this kind of information by dialing 511. This project is still being implemented, so may not be available in your area.
For more information, contact DOT at the state level.
