The stretch of Foothill Boulevard you drive to Vons, to your kid's dentist, to Costco — that road turns 100 this year. Not "runs near a road that turns 100." That is Route 66. The lane you're in was certified as U.S. Highway 66 on November 11, 1926, and the national celebration marking its centennial officially kicked off on April 30, 2026, when Springfield, Missouri was named the host city for a coast-to-coast birthday that lands squarely on our main street.
Most residents know Foothill has some Route 66 heritage. Fewer know that Rancho Cucamonga was picked as a coordinating hub for the Inland Empire leg of the celebration, and fewer still can name the three buildings along that corridor that carry it. This post is a fix for that.
The milepost you drive past every day
The bright yellow building at 8318 Foothill Boulevard is the Cucamonga Service Station, and it is older than Route 66 itself. Built in 1915 as a fuel and repair stop, it predates the highway's 1926 certification by more than a decade. It has since been restored to look the way it did as a 1930s Richfield station and now operates as a free, volunteer-run museum with artifacts of local and Route 66 history.
This year the station has a bigger role. In April 2026 it was named the local headquarters for the Route 66 Centennial across the Inland Empire, coordinating recognition and partnerships with landmarks including the Sycamore Inn here in Rancho Cucamonga and the Wigwam Motel in San Bernardino. That reach out of a 111-year-old former filling station tells you where the city sits in the Mother Road story.
"The iconic and very visible bright yellow Cucamonga Service Station represents the rich history and unique character of Rancho Cucamonga," said Heather Rawlings-Polk, Executive Director of the Rancho Cucamonga Chamber of Commerce, describing the station as the gathering place for the centennial year.
If you have out-of-town family visiting this year and you have already exhausted Victoria Gardens as an idea, this is the answer you didn't know you had. Admission is free.
The 2026 calendar worth marking
The centennial is not a single day. It is a rolling year of local and national anchor dates, and the ones worth writing on your kitchen calendar are these.
| Date | Event | Where |
|---|---|---|
| April 30, 2026 | National Route 66 Centennial kickoff (host city Springfield, MO, with coordinated local recognition) | Cucamonga Service Station, 8318 Foothill Blvd |
| June 27, 2026 | Cucamonga Classic Car Show, 9 a.m.–2 p.m., roughly 100 classic cars, music, food, vendors, free admission | 8318 Foothill Blvd |
| Third Fri/Sat of September | Route 66 Cruisin' Reunion, classic cars along tree-shaded Euclid Avenue | Ontario, one exit west |
| November 11, 2026 | The actual 100th anniversary of Route 66's naming | Nationwide, with local programming |
The June car show is the one to plan around if you have never done it. The organizing group, led by Cucamonga Service Station president Anthony Gonzalez, uses the show as a fundraiser for an expansion the volunteers call "The Garage." Public admission and parking are free. A $45 registration lets you enter a vehicle. Bring a folding chair.
Why the Sycamore Inn is on that list
Two miles east of the service station, on the same road, sits the Sycamore Inn. If you have driven past its neon sign and assumed it was a mid-century steakhouse someone dressed up in old-timey signage, you have the story exactly backward. The sign underplays the history.
The site has been serving travelers on this exact spot since 1848, when a man named William "Uncle Billy" Rubottom converted an existing adobe building into an inn and tavern along the Santa Fe Trail. That trail became Foothill Boulevard. Foothill Boulevard became Route 66. The current building, put up in 1920 by local citrus grower John Klusman, predates the highway's certification by six years. Danish immigrant Irl Hinrichsen bought it in 1939 and gave it the Sycamore Inn name after a remodel. Chuck and Linda Keagle took over in 2002 and re-landscaped and repaired the building.
The wall of framed photos inside the dining room includes an autographed picture of Marilyn Monroe, who ate there in 1959. The stories attached to the property include an unsolved 1862 murder of ranch owner John Rains, whispered vigilante plots, and an alleged Prohibition-era stint as a speakeasy. These are not marketing embellishments. They are the reason food writers keep circling back to the place.
Here is the practical read for a resident. The Sycamore Inn is what people in other Route 66 towns wish they still had. Tucumcari has the Blue Swallow. Seligman has the Snow Cap. Rancho Cucamonga has a working 1920 building on the original alignment, serving dinner tonight, with a wine list that nods to Cucamonga's status as California's first wine region and three wine cellars in the basement. The centennial year is the excuse to actually go.
The bridge you have probably walked over without noticing
Between those two landmarks, the city installed the West Gateway Bridge, a Route 66-themed pedestrian and bicycle bridge that the city describes as a welcome mat for visitors experiencing the corridor's heritage. It is a small piece of civic design that only makes sense once you understand what it is gesturing at. During the centennial year it is worth walking rather than driving.
A weekend built on your own main street
Here is the itinerary a resident can actually run. Start at the Cucamonga Service Station on a Saturday morning. Give yourself 30 minutes with the exhibits. Walk or bike a segment that includes the West Gateway Bridge. Have dinner at the Sycamore Inn that evening, and ask for the booth near the cobblestone fireplace. If you want to extend it, the Route 66 Cruisin' Reunion on Euclid Avenue in Ontario is a straightforward add-on in September, staged along a tree-shaded stretch that reads more like a small-town main street than a modern arterial.
None of this requires driving to Arizona. That is the point. The stretch of the Mother Road that gets photographed for calendars, the one where the highway feels like a highway and not a suburban commercial strip, has a Rancho Cucamonga equivalent that most locals treat as background scenery.
What this year does for how you see your own street
New residents ask what makes Rancho Cucamonga distinct from the rest of the western Inland Empire. The honest answer usually involves the wineries, the mountain backdrop, and Victoria Gardens. The centennial year adds another one, and it is the most durable of the four because the underlying facts are 178 years old.
You live on a road that carried Spanish explorers, Santa Fe Trail wagons, Depression-era migrants headed for California, and postwar families in wood-paneled station wagons on their first big vacation. The buildings that saw all of that are still standing, still open, and still serving. In 2026 the country is going to spend a year talking about that highway. Rancho Cucamonga has one of the more complete surviving segments of it, and the people running the local celebration would rather you show up than not.
Take the kids to the June car show. Book a table at the Sycamore Inn on a random Tuesday. Walk the West Gateway Bridge with your coffee. This is a year to be a tourist on your own street.
