The steep pass was made easier to cross with a deep slot-like road cut by Charles H. Brindley, Andrés Pico, and James R. Vineyard, to whom the State of California awarded a twenty-year contract to maintain the turnpike and collect tolls.[2][3] Thus, the "San Fernando Mountain," the most daunting obstacle along the Fort Tejon Road, the main inland route from Los Angeles to the north, was cut through. Butterfield Overland Mail, a stagecoach that operated mail between St. Louis, Missouri, and San Francisco, began using it directly.
History
In 1861 a landowner and surveyor named Edward Beale was appointed by President Abraham Lincoln as the federal Surveyor General of California and Nevada. Beale challenged General Pico's loyalty to the new president and in 1863, Beale was awarded the right to collect the toll in the pass. Beale maintained rights to the cut for the next twenty years and so it became known as "Beale's Cut." Beale used Chinese immigrants to do most of the work on the cut. Work was completed in 1863, but the LA Board of Supervisors accepted it as complete on March 5, 1864.[4]
The cut had major damage in the winter of 1861–62 and wagons could not get through the pass. In March 1862 soldiers under the command of Major Theodore Coult of the Fifth California Volunteer Infantry, repaired the cut and road. The Fifth California Volunteer Infantry headquarters were Camp Latham, California. The soldiers repaired the cut as ammunition wagons could not get to Fort Yuma, California.[5][6]
Beale's Cut was eventually deepened to 90 feet (27.4 m). It lasted as a transportation passage near present-day Newhall Pass until the Newhall Tunnel opened in 1910.[7]
Beale's Cut appeared in many silent western movies. The location became a favorite of movie producers like John Ford and D. W. Griffith. In Ford's 1923 film Three Jumps Ahead, American cowboy star Tom Mix is filmed jumping over the pass, although it has been widely debated among film historians whether Mix himself made the jump, with any of a number of stuntmen claiming credit for it while some experts believe the jump was achieved purely through special effects.[8] John Ford used the location in at least four films over a twenty-year period beginning as early as 1917.
Still in existence today, it is no longer passable by automobiles. It suffered a partial collapse during the Northridge Earthquake, on January 17, 1994, and now is about 30 feet (9.1 m) deep. It is visible from the Sierra Highway about one mile north from the intersection of The Old Road and Sierra Highway, just after the first bridge under SR 14. It lies between Sierra Highway and the new freeway, about a quarter-mile to the northeast of a stone marker. Beale's Cut is difficult to find today because it is fenced off and not close enough to the Sierra Highway to be easily seen.
The pass originally discovered in August 1769 by Catalan explorer Gaspar de Portolà, the pass today is named for Henry Newhall, a businessman in the area during the 19th century.
In 1910 the 435 ft (133 m) Newhall Auto Tunnel was built a quarter-mile northwest of Beale's Cut. The tunnel was 17.5 ft (5.3 m) wide and two-way traffic through it was slow.
The California Division of Highways decided to replace the tunnel; in July 1938 work started to remove the rock above the tunnel to create a four-lane highway. The road was first known as US Highway 6, then state Highway 14, and finally the present-day Sierra Highway. The cut for the tunnel is west of today's Highway 14.[9]
