The 511 system is a national traveler’s resource set up and run by the U.S. Department of Transportation’s (DOT) Federal Highway Administration (FHWA). The system allows drivers in participating states/cities to dial “511” on their phones and receive real-time traffic information, such as: road closures and accidents.
811 is the phone number you call before digging to protect yourself and others from unintentionally hitting underground utility lines. There are millions of miles of buried utilities beneath the surface of the earth that are vital to everyday living like water, electricity and natural gas.
Emergency Telephone Number for police, fire, medical, rescue and other public safety emergency service providers.
