The New Mexico Department of Transportation (NMDOT) has been honored with the 2025 Perpetual Pavement Award by the Asphalt Pavement Alliance. The award recognizes a nine-mile segment of New Mexico Route 6, which is part of the original Route 66 alignment west of Los Lunas, for its long-term performance and preservation.
The section, opened in 1928 as part of Route 66, has not experienced any structural failure despite nearly a century of use. It has endured harsh temperature changes, challenging soil conditions, and seasonal monsoons.
“We’re proud to preserve the legacy of this iconic roadway while ensuring it continues to serve New Mexicans safely and efficiently,” said Ricky Serna, cabinet secretary.
Dan Lewis, executive director of the Asphalt Pavement Association of New Mexico, stated: “New Mexico’s approach shows how smart engineering can preserve history while building for the future.”
According to NMDOT, this durability results from innovative asphalt technologies, engineered drainage systems, reinforced subgrades, and sustainable maintenance strategies. The pavement structure has never been increased by more than four inches at any time, maintaining both its historic character and modern standards.
The award was presented on September 18 during a meeting of the New Mexico State Transportation Commission. It highlights NMDOT’s commitment to engineering excellence, cultural preservation, and sustainable infrastructure.
Since its inception in 2001, the Perpetual Pavement Award program has recognized only 217 pavements across 36 states and Canada. Roads must last at least 35 years without major structural failures to qualify; New Mexico’s Route 6 far exceeds that benchmark.
“This national recognition places New Mexico at the forefront of infrastructure preservation, just as we approach Route 66’s centennial,” Serna said. “It reflects our values of preserving the past, serving the present, and planning for the future.”
Route 66 was commissioned in 1926 and remains an important symbol beyond its role as a highway. With 474 miles within state borders—the longest remaining stretch—New Mexico will have a prominent role in upcoming centennial celebrations throughout 2026.
