Route 66 turns 100 in 2026 — established November 11, 1926, signage erected the following year — and Seligman, the town that arguably saved the road, had one of the most personal reasons to mark the occasion. The April 30 centennial bash was not a generic milestone ceremony. It was a party for a community that spent four decades fighting to keep this highway alive, held on the original asphalt alignment where that fight began.
Here is what happened.
The Day’s Shape
The event ran from 9 a.m. to 5 p.m., anchored at Seligman Centennial Park and spilling out onto the original Route 66 alignment itself for the afternoon party. The schedule had the kind of layered architecture you get when a small town has a lot to say: official ceremony in the morning, public celebration in the afternoon.
The post office was doing official Seligman Route 66 Centennial USPS stamp cancellations from 9 a.m. to 4 p.m. — one of eight states issuing Forever stamps to mark the highway’s hundredth year, and the only one with a hand-cancel ceremony happening in the town that the preservation movement called home.
At the information booth, community members and Route 66 historians were available for conversation from 9 a.m. through midday. The Route 66 book signings from 11 a.m. to 1 p.m. drew a crowd that was less interested in browsing titles and more interested in conversation — these were people who had read most of the books already.
The Monument Unveiling
One of the morning ceremony’s centerpieces was the unveiling of new monument signs for the Route 66 Centennial. These are not tourist markers. They are meant to be permanent fixtures in the historic district, documenting what the town is and when it was recognized.
The unveiling reflected a question Seligman has navigated since the preservation movement started: how do you honor a road’s history without turning your town into a theme park? The monument signs stay on the architectural register side of that line — permanent, text-based, information-forward rather than souvenir-forward.
The Proclamation for Angel Delgadillo
At 5 p.m., Yavapai County Supervisor Chris Kuknyo presented a formal proclamation to Angel Delgadillo.
Delgadillo — 99 years old during the centennial, one year younger than the highway — organized the 1987 meeting in Seligman that founded the Historic Route 66 Association of Arizona. That meeting launched the grassroots campaign to put “Historic Route 66” signage back on the bypassed road and draw travelers back to the corridor towns that Interstate 40 had stranded. The first Route 66 Fun Run, in April 1988, came directly from that movement.
A county supervisor presenting a proclamation to a barber from a town of 450 people is either a bureaucratic footnote or a genuine moment of recognition depending on who you ask. In this case the room knew the weight of it. Delgadillo spent four decades working to make sure Seligman was still on the map when the road’s hundredth birthday arrived.
The Afternoon Party
From 2 p.m. to 5 p.m., the party moved to the original Route 66 alignment — the same stretch of road that Delgadillo and his neighbors were fighting to preserve in 1987. A live band, food trucks, and a booth from Mother Road Brewery turned the historic main corridor into the kind of afternoon that Route 66 towns are genuinely good at: low-key, local, worth driving to.
That pairing — the serious morning ceremony with the loose afternoon block party — felt right for Seligman. The town has always been more comfortable with the actual road than with the mythology surrounding it.
The Broader Centennial Context
The April 30 date was deliberately chosen to give Seligman its own moment before the corridor filled with Fun Run traffic in early May. The Historic Route 66 Association of Arizona is coordinating a year-long calendar of centennial events across the Arizona corridor — from Seligman in the east to Topock at the California line — with the Fun Run itself running as a centennial edition in early May and the Route 66 Fest in Kingman scheduled for October.
The US Postal Service issued Route 66 Forever stamps commemorating all eight states the highway runs through. The National Park Service’s Route 66 Corridor Preservation Program has documented the highway’s contributions to American transportation and cultural history since 1999. For the centennial, preservation advocates across the eight-state corridor have coordinated restoration projects, historical documentation, and public programming to make the year count.
For Seligman, the centennial also carried some unspoken weight. The town was already notable as the place where Route 66 preservation started; the hundredth birthday of the road confirmed how consequential that 1987 meeting in a barbershop turned out to be.
What It Felt Like
Seligman’s centennial celebration was not a large event by any standard measure — a few hundred people, a park, a post office, an afternoon block party. What it had was specificity. The people who showed up were there because this particular road and this particular town meant something to them, not because an event-marketing campaign pulled them in.
The proclamation for Angel Delgadillo at 5 p.m. closed the day with the kind of acknowledgment that should have come years ago and was all the more meaningful for arriving on the centennial itself.
Who Showed Up
The crowd skewed noticeably international. Route 66 has drawn a European following for decades — German, French, and British travelers in particular have treated the full Chicago-to-Santa Monica drive as a bucket-list trip since long before “bucket list” was the phrase for it — and the centennial pulled some of that audience to Arizona earlier in the year than usual. Conversations at the food-truck line shifted between English, German, and occasional Japanese, which is a fairly ordinary sound on this stretch of highway but still a reminder of how far the road’s reputation travels.
A time capsule viewing and guest book ran alongside the morning program, giving visitors without an official role in the ceremony something to participate in directly. The guest book in particular functioned as an informal centennial record: names, home cities, and — a detail that came up often — how many times each signer had personally driven the road. For a town of roughly 450 people, watching that list fill with entries from well outside Arizona is its own small measure of the day’s reach.
Into the Fun Run Weekend
The centennial bash was timed deliberately to sit just ahead of the Route 66 Fun Run, which departed Seligman the following weekend and ran as a centennial edition of the annual event. Angel Delgadillo has waved off the Fun Run’s start in past years — a gesture that functions as the informal starting pistol of the Arizona Route 66 season — and the back-to-back sequencing meant visitors who came for the centennial and stayed the extra days got both the civic ceremony and the classic-car procession in the same trip.
For first-time visitors who arrived for the centennial and lingered for the Fun Run, that sequence illustrates something that is easy to miss in general Route 66 tourism coverage: Seligman’s relationship to the highway isn’t a themed retail experience built for visitors. It’s a working civic relationship between a small town and the road running through it, maintained across generations by the same families and the same local organizations that founded the preservation movement in the first place.
What to Know If You Missed It
The Route 66 centennial continues through November 11, 2026, the road’s official hundredth birthday. The Historic Route 66 Association of Arizona is coordinating events across the full Arizona alignment for the rest of the year, and additional monument signs — matching the ones unveiled in Seligman on April 30 — are being placed at other corridor towns through the centennial calendar, meaning the Seligman unveiling was the first of the series rather than a one-off.
Seligman itself is reachable year-round from I-40 at Exit 121, and its historic commercial district is a walkable ten-minute loop regardless of what’s on the events calendar. Shop and diner hours vary seasonally in a town this size, so calling ahead before a long detour built around a single stop is reasonable practice anywhere on this corridor, not just in Seligman.
