Sacramento Valley - Transportation

Transportation

Interstate 5 is the primary route through the Sacramento Valley, traveling north-south roughly along the valley's western edge. Interstate 80 cuts a northeast-to-southwest swath through the southern end of the valley, mostly through Sacramento and Yolo Counties, and ends at the San Francisco-Oakland Bay Bridge. Several secondary routes connect the two roads, including Interstate 505 and State Route 113. The Sacramento area has a web of urban freeways.

Other principal routes in the region include State Route 99, which runs along the valley's eastern edge, roughly parallel to I-5, from Sacramento until its northern terminus in Red Bluff; State Route 20, which traverses the valley from west to east on its route from State Route 1 in Mendocino County to the Donner Pass; State Route 49, named in honor of the California Gold Rush and running through many old mining towns in the foothills of the valley; and State Route 45, which runs along the course of the Sacramento River roughly ten miles (20 km) east of I-5.

The Union Pacific Railroad serves the valley, with its principal north-south line from Oakland, California to Portland, Oregon, via Sacramento, Marysville, Chico, and Redding. This is also the route of Amtrak's Coast Starlight passenger train. The Union Pacific also has two east-west lines, through Donner Pass (the former Central Pacific Railroad), and through the Feather River gorge (the former Western Pacific Railroad). Amtrak's California Zephyr uses the Donner Pass route. The BNSF Railway has a line from Klamath Falls, Oregon, to a junction with the Union Pacific Feather River line at Keddie. The BNSF has trackage rights on both the UP east-west routes. In addition, the California Northern Railroad operates the former Southern Pacific Railroad line on the west side of the valley from Davis to Tehama (near Red Bluff).
