I will be hosting an online meeting next month to discuss Highway 99 in Southern California. It will be open to questions about the highway, its history, the Ridge Route, the Highway 99 Association of California, and depending on time – connecting highways like US 6. If you’d like to submit a question, use the form below and we’ll do our best to answer them in the meeting. This is your chance to meet the author of this site and learn more about California’s Main Street!
The meeting will be hosted on Zoom on Wednesday, February 10, 2021 from 5:30 pm to 6:30 pm. Registration will be required. Use the link below to register.
Through the town of Banning, US 99 was first paved with a 16′ concrete slab in 1922, similar to sections east of town. Minor improvements were made a few years later in 1925. Beaumont would get theirs in 1923, albeit a with a 20′ concrete slab. No real changes would take place until early 1940, when a four-lane expressway was constructed between the west side of Banning to the US 60 junction in Beaumont. Remnants of this expressway remain today, mostly visible between Sunset Avenue and Highland Springs Avenue. Generally, the eastbound lanes follow the 1922/23 alignment of US 99.

In mid-1955, construction began on the first section of freeway through the pass. This first section would bypass the two-lane roadway through central Banning, eliminating the last major bottleneck in the region. It was constructed between 22nd St and the east end of Banning. On May 21, 1956, the eastbound lanes of the freeway opened. The westbound lanes finally opened July 3, 1956.

In August 1962, the freeway was extended to bypass Beaumont as well. The freeway was modified again in 1972, when it was widened to eight-lanes and the former eastbound Ramsey St exit near 22nd St was eliminated.
1962 signage at the west end of 6th St, since replaced. The sign on the left formerly had US 60 until it was overlaid by a State 60 shield. The overlay on the right covers a US 70 and US 99 shields.
1962 Signage on I-10 at the 60 split, since replaced. The sign to the left still had a visible US 60 shield under the overlay until late 2020.
Beaumont to Calimesa San Timoteo Canyon to Sandalwood Dr
West of Beaumont, the original alignment of US 99 gets a bit tougher to follow as the construction of I-10 has removed many sections and broken up the continuity.
Desert Lawn Dr
Starting just west of the 10/60 interchange, a short section of original alignment can be followed on Desert Lawn Dr. In 1919, the roadway was graded from Calimesa to Beaumont. Starting in late 1924, the roadway was finally paved with a 20′ wide concrete slab. Improvements were made at the crossings of San Timoteo Creek in 1930 and 1939. In 1950, what is now Desert Lawn Dr from San Timoteo Canyon Road east became the eastbound/southbound side of the US 99 expressway. Finally in 1965, the new I-10 freeway was built, obliterating both the old expressway and many sections of original alignment. Desert Lawn Dr essentially became a frontage road.

Roberts Rd / Cooper Dr
Roberts Road west of Cherry Valley Blvd to near Singleton Rd follows the 1925 alignment of US 99. This section has the last intact and fully exposed concrete from that era. Its days seem to be numbered as well, as a major development adjacent threatens to realign and bury this concrete. For now, it remains as a window to US 99’s past. This section was bypassed by an alignment now buried by I-10 in 1937, which was subsequently upgraded to an expressway in 1950.
Sections like this need to be saved, if possible. This is where the Historic Highway 99 Association of California can come in. If you’d like to join that effort and work to save what is left of old US 99, check them out at https://historic99.org.

Calimesa Blvd Cherry Valley Blvd to Live Oak Canyon Rd
Between Cherry Valley Blvd and Live Oak Canyon Road, the old alignment of US 99 follows Calimesa Blvd. The sections from just north of El Casco Creek to Sandalwood Dr, with the exception of the area around Singleton Rd, are all that remain of the westbound/northbound side of the 1950 expressway. Impressively, from Chandler Ave to Sandalwood Dr, long sections of 1950 metal guardrail still remain along the west/south side of the roadway.

Calimesa marks the boundary between Riverside and San Bernardino counties. The main road, Calimesa Blvd, follows the original alignment of US 99 with little deviation most of the way to Live Oak Canyon Rd. In 1951, the town was bypassed by a new expressway, which diverged from the original alignment Myrtlewood Dr and Wildwood Canyon Rd. In 1965, the expressway was reconstructed as the I-10 freeway, and the Calimesa bypass was shifted east to Sandalwood Dr. The freeway was also shifted slightly south, converting the former NB/WB lanes of the US 99 expressway to a frontage road. Many remnants of the expressway are still visible today in the form of small culverts crossing an adjacent drainage ditch. At Yucaipa Creek, an original 1920’s bridge/culvert complete with railing is still intact.

Further north/west, a small section of the 1925 concrete is still visible on the right side of the roadway where the roadway was realigned slightly at a curve.

US 99 near Garnet, CA. First paved in 1922 with a 16′ slab and widened in 1926 to a full 20′. Asphalt was added in the past few years. Today, it is known as Varner Road and this concrete is exposed from Palm Dr to near I-10 / Mission Creek.
Postcard view of Mission Valley from around I-805 looking easterly
I acquired this postcard recently and wanted to share. It depicts Mission Valley in San Diego. While the exact date is unknown, it is likely from the early 1920’s. So much has changed in this view. It appears to be near I-805 at the south side of the valley and is looking east toward Mission Trails Regional Park. The stadium would be just outside the view to the left. The road along the bottom of the postcard roughly follows Camino Del Rio, which was the predecessor to US 80 / I-8 in the valley.
The Saugus Cafe, which has been in business for 132 years, is in danger of closing. With the ongoing crisis, business has slowed and restrictions are in place making it tougher than ever. This restaurant is a part of the history of Santa Clarita and US 99. It is located at 25861 Railroad Avenue (formerly San Fernando Road) in Santa Clarita, California. As a kid, I always enjoyed going there and getting a seat near the window so I could watch the trains go by. I was last able to stop there in January 2020. It isn’t truly a Ridge Route trip without it, as it is the LAST place that is still around that dates to that era AND is along the route.
If you’d like to help save this historic restaurant and learn more, KHTS radio has a detailed article here. The Saugus Cafe has also started a “GoFundMe” account. If you are in the area, please stop by the restaurant and show your support! We need places like this to keep going, as without we lose a part of our heritage and a connection to the past.
