Special routes of U.S. Route 50

U.S. Route 50 Business (US 50 Bus.) was a business route of US 50 in Oakland, California. It existed when US 50 use to extend west to San Francisco. The business loop's western terminus was at the MacArthur Maze interchange. From there, it ran concurrently with State Route 17 (present-day Interstate 880) along Cypress Street, later the Cypress Freeway, to Broadway in Downtown Oakland. US 50 Bus. then headed north on Broadway and then east on Grand Avenue towards the end of Lake Merritt. The business route then turned south on El Embarcadaro and then east on Lakeshore Avenue before rejoining US 50 at MacArthur Boulevard, later the MacArthur Freeway. The business route was decommissioned when US 50 was truncated back to West Sacramento and Interstate 580 replaced the US route through Oakland.

U.S. Route 50 Business (US 50 Bus.) was a business route of US 50 in Sacramento, California.

U.S. Route 50 Alternate (US 50 Alt.) was an alternate route of US 50 in the U.S. state of California. The route is used as a detour around flooding in the American River canyon, which the main route of US 50 uses to scale the Sierra Nevada. It has been activated and deactivated on multiple occasions and concealed signs have been permanently installed so the route can be reactivated as needed.[1][2] The route has never been officially approved by AASHTO. The route follows a local road called Mormon Emigrant Trail from Sly Park up a ridge to eventually connect with California State Route 88 over Carson Pass, using a small portion of California State Route 89 over Luther Pass to reconnect with US 50 near South Lake Tahoe.

U.S. Route 50 Temporary (US 50 Temp.) was a temporary route of US 50 in the U.S. state of Nevada. It was in use when from 2009 to 2018 when Interstate 580 was partially built and terminated at the Fairview Drive exit. It followed Fairview Drive to connect the freeway alignment with the Carson Street Alignment. It was removed once I-580 was completed.

U.S. Route 50 Business (US 50 Bus.) was a business route of US 50 in the U.S. state of Nevada, and carried the unsigned designation of SR 530. It followed the original alignment of US 50 along William Street once US 50 was moved to an alignment concurrent with Interstate 580. It was removed as part of a mileage swap between the Nevada Department of Transportation and Carson City public works in 2010.

U.S. Route 50 Alternate (US 50 Alt.) is an alternate route of US 50 in the U.S. state of Nevada.

U.S. Route 50 Alternate (US 50 Alt.) was a 292-mile (470 km) alternate route of US 50 in Nevada and Utah. It existed from the 1953 to the 1976 and followed the original routing of US 50 from Ely, Nevada to Moark Junction, Utah (roughly 11 miles [18 km] south-southeast of Provo in what is what is now the east edge of Spanish Fork), via Salt Lake City. US 50 Alt. ran along what is now U.S. Route 93, U.S. Route 93 Alternate, Interstate 80, Utah State Route 201 and U.S. Route 89.

US 50 Alt. was created when US 50 was routed in 1953 to run concurrent with U.S. Route 6 between Ely and Moark Junction and the former US 50 routing was designated east US 50 Alt. The designation was deleted in the 1970s, about the time that US 50 was again rerouted (to its current routing) in 1976.

U.S. Route 50 Temporary (US 50 Temp.) was a 17.1-mile (27.5 km) temporary route of US 50 in Utah, departing the alignment of what is now U.S. Route 6 (UT 6) at the site of the former community of Kyune (roughly 3.7 miles [6.0 km] southeast of Colton) along what is now called Emma Park Road and returning to US 6 in southern Castle Gate via what is now U.S. Route 191 (US 191).

The first road built between Helper and Soldier Summit exited the Price River Canyon along modern US 191 near Castle Gate and returned to the current alignment of UT 6 via Emma Park Road to bypass a narrow, meandering portion of the canyon. Once announced this road would be used for the Midland Trail (precursor to US 6) a shorter, more direct route was proposed that remained in Price Canyon for the entire ascent.[3][4] Once finished both routes were briefly used for US 50. This portion of then US 50 is today designated US 6. The road is occasionally as a detour when US 6 through Price Canyon is closed. Specifically this alternate route was used for a period of time in 1966 while the main route in Price Canyon was being improved.[5] Emma Park Road is currently designated as a county road within Utah and Carbon counties.
