The Adventure Cycling Association recently announced the designation of 18 new U.S. Bicycle Routes in five states, including nearly 330 miles in California to U.S. Bicycle Route 66.
This is what is stated about the California section:
USBR 66 (329.8 miles): Where possible, USBR 66 generally follows the historic U.S. Route 66. Beginning at the Arizona border, the route crosses the Colorado River then travels along the high-desert National Trails Highway, passes through Barstow, Victorville, and San Bernardino, follows the Pacific Electric Bikeway across the eastern end of the San Gabriel Valley, and reaches Los Angeles, where highlights include Olivera Street, Chinatown, Hollywood, and Beverly Hills, before it ends on the pier at Santa Monica.
More about U.S. Bicycle Route 66, including its fold-out maps, can be found here.
The other new routes include Indiana, Ohio, Utah and Washington.
The U.S. Bicycle Route System seeks a national network of officially recognized, numbered and signed bicycle routes, with the goal of 50,000 miles of routes linking every state in the country.
Such routes help promote tourism, enhance rider experience and safety, and assist in building out and planning other transportation facilities. All U.S. Bicycle Routes are designated by state departments of transportation and approved by the American Association of State Highway and Transportation Officials.
