The journey begins at the Pacific Ocean and then traverses Golden Gate Park. Afterwards, you will cross the city and eventually pass by the western termini for Route 40 (where Harrison and Bryant Streets cross 10th Street). You will follow Bryan eastward and board the Alameda/Oakland Ferry (the Bay Bridge does not allow pedestrian traffic). In Oakland, you will travel up San Pablo Avenue all the way to the Carquinez Bridge (which has a bike lane). From Vallejo, frontage roads, the original alignment and a few detour back roads lead you into Davis. If you follow this itinerary, you do so at your own risk. Failure to exercise good judgment can result in traffic violation citations, injury and even death. If in doubt, please consult with state and local law enforcement agencies.by fbrusca
