18th century
In 1772, Lieutenant
Pedro Fages crossed the pass in pursuit of military deserters, and named it ''Portezuelo de Cortes'' (Cortes Pass). Fages also named the canyon beyond the pass leading down into the Tulare Basin, ''Cañada de las Uvas'' (Canyon of the Grapes) for all the wild California grape vines (
Vitis californica)
growing in it.

; Scott, Harrison Irving; "The California Historian," www.californiahistorian.com website, accessed November 14, 2011; Quote: "The first white man through this area was a Spanish officer and acting governor of Alta California in 1772, Don Pedro Fages. He noticed an abundance of Cimarron grapes growing wild in the area north of what is now Gorman. He named the place ''Canada de Las Uvas'', or Grapevine Canyon. Grapevines were so prevalent the wagoneers and soldiers had to hack their way through. Wild grapes still grow on the sides of I-5 in the pass."

and the
Mission Santa Clara de Asis began to be used for travel north and south along the western San Joaquin Valley. It crossed over the pass and turned westward up
Cuddy Canyon, (avoiding the Cañada de las Uvas) and then descended
San Emigdio Creek into the San Joaquin Valley.
Old Tejon Pass
In 1806, Father Jose Maria Zalvidea, diarist for the expedition of First Lieutenant Francisco Ruiz into the San Joaquin Valley, named the canyon, creek, and pass which had been discovered in 1776 by the explorer priest, Father
Francisco Garces. He recorded the name as "Tejon" (badger)—after a dead badger found at the canyon's mouth. This original Tejon Pass (later called "Old Tejon Pass"), was situated 15 miles to the northeast of what is now Tejon Pass. The old pass went through the Tehachapi Mountains, at the top of the divide between
Tejon Creek Canyon in the San Joaquin Valley and
Cottonwood Creek Canyon in
Antelope Valley
The Antelope Valley is located in northern Los Angeles County, California, and the southeast portion of Kern County, California, and constitutes the western tip of the Mojave Desert. It is situated between the Tehachapi, Sierra Pelona, and t ...
.
Before 1854, the main route of travel into the San Joaquin Valley had come directly north from
Elizabeth Lake (originally ''Laguna de Chico Lopez'') across the Antelope Valley, over this original Tejon Pass, and down into Tejon Canyon, and then proceeded west along Tejon Creek—into the lands of the
Rancho Tejon, that had been granted in 1843. This route to the pass diverted from the El Camino Viejo at Elisabeth Lake, and from 1849 to before 1854 it was the main road connecting the southern part of the state to the trail along the eastern side of the San Joaquin Valley to the goldfields to the north.

Herbert G. Comfort; Enterprise Press; Moorpark, Ca; 1934; (#255); Chapter IV, "The Founding of Fort Tejon; pp. 21-52. "Before 1854, the main line of travel into the valley was straight North from Elizabeth Lake across Antelope Valley, entering the San Joaquin by way of the original Tejon Pass, at the head of Tejon Creek, above the present headquarters of Tejon Rancho. The establishment of the Fort Diverted this general travel to the West almost 29 miles to the present Tejon Pass, then known as Fort Tejon Pass. As the Tejon Creek Pass was abandoned, the name Tejon Pass came to be used solely for
the pass leading into Canada de las Uvas."

Castaic Pass
In 1843,
Rancho Castac was established in La Cañada de las Uvas. During that same year, the first grant of
Rancho Los Alamos y Agua Caliente included the pass, which was now called ''Portezuela de Castac'' (Castaic Pass).

20th century

The
Ridge Route was the first automobile highway linking the
Central Valley with the
Los Angeles Basin. It was laid in a sinuous fashion through the ridges and gullies of the
Sierra Pelona Mountains to the Tejon Pass around 1910. The northern portion of this highway, which became a part of
U.S. Route 99
U.S. Route 99 (US 99) was a main north–south United States Numbered Highway on the West Coast of the United States until 1964, running from Calexico, California, on the US–Mexico border to Blaine, Washington, on the U.S.-Canada border ...
, was known as "
The Grapevine." The Ridge Route was replaced by a three-lane alternate highway in 1933, a four-lane expressway in 1947, and later by the eight-lane Interstate 5 Freeway in 1970.

A section of the highway known as "Dead Man's Curve," was the "scene of many accidents on the narrow old road,"
[ and in July 1932 it took the life of Jack Klieby, 33, who deliberately drove his truck, transporting gasoline, off the roadway to avoid hitting oncoming automobiles. He died when the truck burst into flames.
The curve ''(in adjoining photo)'' was eliminated in 1935 with improvements completed from Fort Tejon to Grapevine station. That work "supersedes the worst portions of the old twenty-foot Grapevine Canyon Highway, shortens the length of the road by approximately eight-tenths of a mile and eliminates 2,937 degrees of curvature or the equivalent of eight complete circles," according to R.M. Gillis of Fresno, District 6 highways engineer.]["Deadman's Curve on Ridge Route Now Eliminated," ''The Fresno Bee,'' September 11, 1935, image 10]

Weather impacts
The pass is sunny in summer, spring, and autumn, but is subject to severe weather and closure to traffic in winter. The 40-mile stretch of Interstate 5 between Grapevine and Castaic is sometimes closed by the California Highway Patrol

, generally because of the icy conditions combined with the steep grade of the pass, and the high traffic during the winter holidays. The Highway Patrol is also concerned, especially with the number of big-rigs that pass through, that one accident in the snowy conditions might force traffic to slow down or come to a complete stop, leaving hundreds of vehicles stalled at once. Whenever there is such a closure, traffic must either wait for it to reopen, or endure a multi-hour detour.[''Grapevine Closures: It's for Our Own Good'']
