History
Soledad Canyon was a vital part of Los Angeles' transportation history. Transit between Los Angeles and the Central Valley was always difficult–in the "Gold Rush era" and stagecoach days the ride was extremely difficult, almost straight up-and-down through
San Fernando Pass, up San Francisquito Canyon, and over
Tejon Pass
The Tejon Pass , previously known as ''Portezuelo de Cortes'', ''Portezuela de Castac'', and Fort Tejon Pass is a mountain pass between the southwest end of the Tehachapi Mountains and northeastern San Emigdio Mountains, linking Southern Calif ...
. In 1856, Lieutenant Williamson, on a railroad surveying party, "discovered" that the pass, sometimes named "Williamson Pass", could provide the lower grades to make Los Angeles–Central Valley train travel possible by the roundabout detour all the way to Mojave, and over Tehachapi Pass, almost 70 miles farther than the direct Interstate 5 used today by trucks and autos.

City of Santa Clarita. In 2015, the Bureau of Land Management issued a cancellation of the contract, effectively ending almost century of mining within the canyon.
Transportation

Soledad Canyon is traversed by the Soledad Canyon Road. The second-longest street in Santa Clarita, it branches from Sierra Highway and
State Route 14 in Acton, heading west into Santa Clarita and serving as a major thoroughfare in the
Canyon Country and
Saugus neighborhoods, ending at Bouquet Canyon Road where it becomes Valencia Boulevard. Other routes through the canyon include State Route 14 (the Antelope Valley Freeway), and the
Metrolink Antelope Valley Line. Travelers on board the Antelope Valley Line are afforded a view of much of the
Santa Clara River.
Vincent Grade/Acton station serves communities within the canyon.
The canyon was chosen as the state's preferred alternative for the route of the planned
