The highway system functions as California’s transportation backbone for commuters and commerce, providing connections to rail, transit, and a number of airports and harbors. The highway system also serves as a gateway to interstate and international transportation. The California Department of Finance estimates that its use will increase from 164 billion annual vehicle miles traveled in 2000 to 207 billion annual vehicle miles traveled in 2010.
