Highway traffic congestion burgeoned as Americans' odometers neared three trillion miles during 2005, according to data from the Federal Highway Administration (FHWA).
The figures represent a 27.4-billion-mile increase over travel in 2004 and nearly 25 percent more than ten years earlier. In the highway mix were registrations of 1.9 million truck tractors and 5.3 million commercial trailers.
The FHWA report, which consists of statistical data on motor fuel, motor vehicles, driver licensing, highway-user taxation, and state and local government highway finance, has been produced each year since 1945. Click here for the FHWA Web site and the travel report.
