New FHWA Report Reveals States with the Busiest Highways
California, Texas and Florida Highways Among Nation's Most Heavily Traveled
"Better information means cities and states can more efficiently target congestion and help people get home from work faster," said U.S. Transportation Secretary Anthony Foxx. "Over the past four years, DOT has improved more than 331,000 miles of roads with federal funds, but we know there's a lot of work that still needs to be done. Information like this, along with new construction and design technologies, help us stretch our dollars further, making a bigger difference for even more people."
Traffic volume data from 2011, the most recent year available, show that the I-5 in California was the nation's busiest interstate, with 21.4 billion miles traveled that year. California's neighboring I-10 and I-110 followed as the second and third busiest, respectively. Los Angeles' section of I-405 serves an estimated 379,000 vehicles per day, making it the busiest interstate in any American city.
