Each year, the State Highway Administration of the Department of Transportation designs and constructs new roads, and operates, maintains, widens, and improves existing highways at an average cost of $905 million a year. To alert motorists to traffic congestion, incidents, and detours, the Administration operates a low-frequency radio station (560 AM) and cooperates with the Coordinated Highways Action Response Team (CHART) Board to provide live images of traffic congestion on the Internet and advance traffic management techniques. On most major highways, the maximum speed limit is 55 miles per hour. On certain sections of expressways and interstate highways, it changed to 65 miles per hour in 1995.
