As part of the overall 511 service, 511 Traffic provides on-demand, up-to-the-minute traffic conditions and driving times for your route. The 511 Traffic Web site complements the 511 phone service and offers free information and tools. The tools are listed in the green section of the left-hand column and can be accessed from every page in the traffic site.
