U.S. Highway 50

U.S. 50 California

U.S. 50 begins in West Sacramento, starting together with Business Loop I-80 and unsigned Interstate 305 into the capital city of Sacramento. U.S. 50 splits away from the business loop freeway near Downtown, and it continues as its own freeway from that point east to Placerville, serving several eastern suburbs of Sacramento including Rancho Cordova and Folsom. Through Placerville, U.S. 50 loses its freeway status and regains it briefly east of town. Eventually, U.S. 50 becomes a two-lane mountain highway, passing through the American River Canyon and passing over Echo Summit before entering Tahoe Valley. The South Shore of Lake Tahoe is served by U.S. 50, and the highway enters Nevada in the shadow of several casinos at the state line.

U.S. 50 California Guides

U.S. 50 no longer exists west of Sacramento; it used to extend all the way to San Francisco. From Sacramento, U.S. 50 used to travel south along a shared alignment with California 99 (then U.S. 99) to Stockton, then turned southwest to Tracy (roughly along the Interstate 205 corridor), then west and northwest via Interstate 580 to Oakland. The final distance into San Francisco via the San Francisco-Oakland Bay Bridge was designated as both U.S. 40 and U.S. 50 until the bridge was renumbered as part of Interstate 80.

In addition to local street names, portions of U.S. 50 follow the Lincoln Highway through California. The remainder of the Lincoln Highway accompanied U.S. 40 across the state.

U.S. 50 Alternate

U.S. 50 has one bannered auxiliary route: U.S. 50 Alternate. This highway is only signposted during events that close the mainline route through the American River Canyon or Echo Pass (between Pollock Pines and South Lake Tahoe). From Pollock Pines, U.S. 50 Alternate follows El Dorado County E-16 (Sly Park Road) south, Mormon Emigrant Trail east, California 88 (Carson Pass Highway) east, and California 89 north to rejoin U.S. 50 at South Lake Tahoe. U.S. 50 Alternate is not a permanent alternate route as typically seen elsewhere in the country. Instead, U.S. 50 Alternate in California is only signed when conditions warrant as a 66-mile Detour U.S. 50 route. It may be signed for traffic control purposes or during conditions that warrant road closure, including fires, floods, landslides, road construction, and accidents. Most of the signs for U.S. 50 Alternate appear to have been installed around 1997 in conjunction with a project to repair several landslide issues in the American River Canyon. Few if any of the signs placed then have been replaced or added since that time.
