The original route from the [[Central Valley (California)|Central Valley]] to the [[San Francisco Bay|Bay]] skirted the [[Sacramento-San Joaquin River Delta|Delta]] by heading south out of Sacramento through [[Stockton, California|Stockton]] and crossing the [[San Joaquin River]] at [[Lathrop, California|Mossdale]], then climbed over the [[Altamont Pass]] and reached the east side of the San Francisco Bay through [[Niles Canyon]]. The Western Pacific was originally chartered to go to [[San Jose, California|San Jose]], but the Central Pacific decided to build along the East Bay instead, as going from San Jose up the [[San Francisco Peninsula|Peninsula]] to [[San Francisco]] itself would have brought it into conflict with [[San Francisco and San Jose Railroad|competing interests]]. The railroad entered [[Alameda Terminal|Alameda]] and [[Oakland Point, Oakland, California|Oakland]] from the south, roughly paralleling what would later become [[U.S. Route 50 in California|U.S. Route 50]] and later still Interstates [[Interstate 5 in California|5]], [[Interstate 205 (California)|205]], and [[Interstate 580 (California)|580]]. A [[Capitol Corridor|more direct route]] was obtained with the purchase of the [[California Pacific Railroad]], crossing the [[Sacramento River]] and proceeding southwest through [[Davis, California|Davis]] to [[Benicia, California|Benicia]], where it crossed the [[Carquinez Strait]] by means of an enormous [[Solano (ferry)|train ferry]], [[Port Costa, California|then]] followed the shores of the [[San Pablo Bay|San Pablo]] and [[San Francisco Bay|San Francisco]] bays to [[Richmond, California|Richmond]] and the [[Port of Oakland]] (paralleling [[U.S. Route 40 in California|U.S. Route 40]] which ultimately became [[Interstate 80 (California)|Interstate 80]]). In 1930, a [[Benicia-Martinez Bridge|rail bridge]] across the Carquinez replaced the Benicia ferries.
