Traveler Information Questions and Answers
On June 1, 2013, MoDOT ended 511 traveler information phone service in the greater St. Louis area. The company providing the free service to the state could no longer do so, and the department chose to use other methods to get traveler information to drivers than to use taxpayer funding for 511 services.
Q: How do I get traveler information around St. Louis?
There are several options available to the traveling public to get information on road conditions on state highways in and around St. Louis. Drivers can use MoDOT’s Traveler Information map for information on most state roadways around Missouri – for more specific information about St. Louis, they can use MoDOT’s Gateway Guide. Both sites have mobile versions for people with smart phones. Drivers can also sign up for text or e-mail alerts on St. Louis interstates and major numbered state roadways at Gateway Guide.
Q: How often is the information updated?
A: Traveler information on the MoDOT’s Gateway Guide and the Traveler Information Map is updated in real time.
Q: Which roads in St. Louis can I get information for?
A: Currently, travelers may get information on all interstates; Route 67 (Lindbergh), Routes 94, 100 (Manchester), 141, 364, 367 and 370; and the Poplar Street Bridge. They may also get information on I-70 and I-55 in Illinois near the Missouri border. Additional state routes in St. Louis will be added as sensors get activated along those routes.
Q: How does the traveler information available differ from the travel information I get on the radio and television?
A: Radio and television will continue to provide valuable sources of information, but with both MoDOT’s Gateway Guide and the Traveler Information Map, you control the information you get. If you travel on I-270 and I-44 you can see for information on those two routes only. You can sign up for text alerts on the routes you use most often, during the times you usually use them. This gives you more route-specific information than you hear in a 30-second traffic news slot, and you will be able to access the information on demand, whenever you need it.
Q: What is 511?
A: 511 is an easy-to-remember travel information telephone number used in many states.
Q: Is there 511 service in St. Louis?
A: No. MoDOT has ended 511 service in the St. Louis area. The service was provided to the department for free as a public service between the telecommunications industry and traffic information. If you are in Illinois on I-55 or I-70, you may be able to access some Illinois 511 services by cellular phone.
Q: When and why was 511 initiated?
A: In 1999 the U.S. Department of Transportation petitioned the Federal Communications Commission for a three-digit dialing code to make it easier for consumers to access travel information services. The FCC assigned "511" to the transportation community on July 21, 2000.
Q: Who is in charge of 511 deployment?
A: States have the lead role in coordinating 511 deployments. National leadership is provided by the 511 Deployment Coalition. Led by the American Association of State Highway and Transportation Officials (AASHTO), and including travel information experts from more than 30 organizations, the Coalition has developed voluntary guidelines for state transportation agencies to follow when they plan 511 service for their states or regions. Other leading member organizations of the Coalition include the American Public Transportation Association (APTA), the Intelligent Transportation Society of America (ITS America), and the U.S. Department of Transportation.
