All routes on the State Highway System are open to bicycle travel except areas where specifically prohibited. The Caltrans District 5 Bicycle Map shows State highway segments in Santa Barbara, San Luis Obispo, Monterey, San Benito, and Santa Cruz counties where bicycling is prohibited and alternative routes. The map is currently out of print and undergoing a revision. However, the map can be downloaded and printed on standard letter-sized paper.
It should be noted that the Caltrans District 5 Bicycle Map only details areas of bicycle travel on the State Highway System. Travelers should consider consulting local agency maps, which offer more detailed bicycle route information for all roads in each county.
