Interstate 10 or I -10 is an Interstate Highway in the U.S. state of California. The highway forms an east-west connection through Southern California, from Santa Monica via Los Angeles and San Bernardino to the Arizona border at Blythe. A significant portion of I-10 passes through the urbanized area around Los Angeles. I-10 is a total of 390 kilometers long.
By Santa Monica Freeway.
It stacks between I-10 and I-15 near Ontario.
I-10 over San Gorgonio Pass.
Santa Monica Freeway
In Santa Monica, traffic from State Route 1 (Pacific Coast Highway) tunnels inland onto I-10. Through Santa Monica, I-10 continues to widen, first 2×2, later 2×3, and finally 2×4 lanes. One then enters the city of Los Angeles, to the west of Los Angeles is a major interchange with Interstate 405. I-10 then has 2×5 lanes and is an extremely busy freeway to Downtown Los Angeles, 15 kilometers away. I-10 sometimes has parallel structures around connections, especially on the eastern half from Arlington Avenue to I-110. On the west side of Downtown Los Angeles follows the interchange with Interstate 110, after which I-10 runs along the south side of downtown. Downtown Los Angeles mainly consists of industrial estates with warehouses. The highway here has 2×5 lanes and largely runs on viaducts. One then crosses the Los Angeles River, whereupon I-10 splits to Interstate 5, State Route 60, and US 101.

San Bernardino Freeway
I-10 then merges with I-5 for a few miles to a junction in East Los Angeles. I-10 is then a wide highway, with 2×6 lanes for regular traffic and two express lanes for toll-paying traffic. Near the suburb Alhambra one then crosses the Interstate 710. I-10 then has mostly 2×4 to 2×5 lanes on a long suburban stretch between Los Angeles and San Bernardino. Continue this 90-kilometre stretch through uninterrupted built-up areas. Interstate 210 and State Route 60 run parallel to I-10, providing three freeways between Los Angeles and the Inland Empire. I-10 runs through a series of suburbs and crosses several major freeways, such as Interstate 605 at El Monte, theState Route 57 and State Route 71 at Pomona and Interstate 15 in Ontario.
The western portion of the San Bernardino Freeway between Los Angeles and Ontario passes primarily through residential areas, the eastern portion from Ontario to San Bernardino primarily passes through industrial estates. LA/Ontario International Airport is also directly accessible from I-10. On the south side of the city of San Bernardino, it interchanges with Interstate 215, after which State Route 210 ends on the east side of San Bernardino at I-10.
San Gorgonio Pass
East of San Bernardino, the suburbanization is still quite far-reaching, but gradually the places along I-10 are less dependent on Los Angeles. East of Redlands, I-10 begins to ascend to San Gorgonio Pass, an elongated upland valley that marks the transition from urbanization from Los Angeles to the Mojave Desert. This route is over 50 kilometers long. I-10 still passes by several distant suburbs of Los Angeles, such as Yucaipa, Beaumont and Banning. The landscape also gets more mountainous, with the 3,505-foot San Gorgonio Mountain to the north. The landscape is also gradually becoming more barren, with large wind farms in the San Gorgonio Pass. State Route 60. ends at Beaumontback on I-10, the region’s last highway interchange. I-10 has 2×4 lanes through the San Gorgonio Pass. Near Whitewater, State Route 62 branches off to Yucca Valley and Twentynine Palms, which is usually seen as the route’s terminus through the San Gorgonio Pass.

I-10 then travels 50 kilometers through the somewhat urbanized Coachella Valley. This part is a mix of desert, suburbanization and irrigated agriculture. Characteristic are the so-called ‘golf resorts’, large suburban areas with golf courses. I-10 passes Palm Springs, Thousand Palms, Palm Desert and Indio. I-10 has 2×4 lanes to Thousand Palms, then 2×3 lanes to Coachella. Here State Route 86 branches off to the Salton Sea, beginning the transition from the Coachella Valley to the Mojave Desert.
The route to the Mojave Desert begins to ascend as Coachella is slightly below sea level. I-10 rises here to 500 meters above sea level. Suburbanization abruptly gives way to barren, uninhabited desert. I-10 only has 2×2 lanes here. The highway leads past Joshua Tree National Park. There are several large solar parks in the Mojave Desert. Between the Coachella Valley and the Colorado River valley, there are actually no places of interest along I-10. State Route 177 joins at the hamlet of Desert Center. I-10 gradually descends long straights through the barren valleys into the irrigated Colorado River valley. I-10 passes through the town of Blythe, then follows the bridge over the Colorado River, which forms the border with the state of Arizona. TheInterstate 10 in Arizona then continues to Phoenix.
Santa Monica Freeway
See Santa Monica Freeway#History.
The first section of the Santa Monica Freeway opened in 1961 and the interchange opened with the San Diego Freeway in 1964. In 1966, the entire highway between the Pacific Coast Highway and Interstate 5 on the east side of downtown was completed.
San Bernardino Freeway
See San Bernardino Freeway#History.
On July 15, 1952, it was decided that I-10 should become a highway, and in 1959 it became part of the California Freeway and Expressway system as well as the Interstate Highway system. In 1954, the highway was renamed the San Bernardino Freeway. In 1958, the San Bernardino Freeway was completed between Los Angeles and San Bernardino.
Between 2003 and 2013, I-10 east of San Bernardino was widened. On June 11, 2013, the final section between Yucaipa and Redlands was widened to provide 2×4 lanes of traffic on the entire route.
San Bernardino – Indio
Some of the works of art on the highway date from before the highway itself was built, several bridges east of Banning were already put into use in 1935 and 1940.
The oldest section of the highway between San Bernardino and Indio is the Banning bypass that opened in 1956. The rest opened mainly in the 1960s. In 1961, the section east of State Route 60 opened to Banning, as did the first section west of Indio. In 1962 the route through the south of San Bernardino followed. The highway between San Bernardino and Banning was completed in 1965. Finally, the Indio bypass opened to traffic in 1972.

Indio – Blythe (Arizona)
The route through the Mojave Desert was built in the 1960s. The oldest part is the bridge over the Colorado River on the border with Arizona, which opened in 1960. After that, the highway was built through the desert between 1964 and 1969. The part along Blythe was the last part to open, in 1972.
