A Stretch of Route 66 Once Played “America the Beautiful” as You Drove Over It

Did you know that over 250,000 drivers experienced New Mexico's musical stretch of Route 66 during its peak in 2014? You'd hear "America the Beautiful" playing through your tires at exactly 45 mph, thanks to carefully spaced rumble strips engineered by a team of musical experts. While this quarter-mile segment near Tijeras captured nationwide attention for its innovative design, there's an intriguing story behind how this singing highway came to life – and why it eventually fell silent.

The Birth of New Mexico's Musical Highway

When National Geographic Channel partnered with the New Mexico Department of Transportation in 2014, they created something truly unique. Their musical inspiration led to a quarter-mile stretch of Route 66 that could actually play "America the Beautiful" as you drove over it.

Through community collaboration with San Bar Construction Corp., they installed special rumble strips between mile markers 4 and 5 near Tijeras. The construction team used metal templates and blowtorches to create precise grooves in the heated asphalt. The innovative project attracted global visitors who came specifically to experience this musical marvel.

They completed the entire project in just one day, marking the musical section with painted notes on the pavement.

You'd need to drive exactly 45 mph to hear the tune properly, as each vehicle's tires created slightly different sounds when rolling over the melodic strips. Unfortunately, the road has been gradually fading away, and there are currently no plans to restore it due to the high costs involved.

Engineering Marvel: How the Musical Road Works

The science behind New Mexico's musical road relies on precise acoustic engineering and careful measurements. When you drive over specially designed rumble strips at exactly 45 mph, they create musical notes through carefully timed vibrations.

The acoustic design uses strips placed 2.4 inches apart to generate specific frequencies – like 330 vibrations per second for an "E" note.

The engineering team created this innovative traffic calming feature by carefully considering:

• Strip spacing and depth to produce the right pitch
• Road surface materials that enhance sound quality
• Quarter-mile length needed for the complete melody

You'll need to maintain exactly 45 mph to hear "America the Beautiful" properly.

This creative approach to road design reflects how service-learning projects can effectively connect classroom concepts to real-world applications.

While the grooves experience wear over time, this musical marvel showcases how creative engineering can blend safety with entertainment on America's historic highways.

The project is one of only five musical roads in existence worldwide, making it a unique attraction for both tourists and engineering enthusiasts.

Creating Music With Rumble Strips and Speed

Musical roads transform everyday rumble strips into precise instruments through carefully calculated spacing and engineering. When you drive over these special grooves at exactly 45 mph, they create recognizable tunes through sound engineering principles.

The closer together the grooves are, the higher the pitch you'll hear. Think of it as a giant musical composition carved into the pavement. Your car's speed determines how the song plays – drive too fast, and you'll get a higher-pitched, faster version. Go too slow, and it'll sound deeper and dragged out. This technique was first demonstrated in Denmark in 1995, marking the beginning of musical road innovations. The famous Route 66 installation offered drivers a chance to hear America the Beautiful when maintaining proper speed.

The most challenging part is getting the measurements just right, as even small errors can make the tune unrecognizable. Weather and wear can affect the sound quality too, which is why these musical roads need regular maintenance to keep playing their songs correctly.

Route 66's Unique Tourist Attraction

Beyond musical roadways, Route 66 offers a treasure trove of quirky and memorable attractions. You'll find roadside nostalgia at every turn, from enormous concrete whales to classic diners serving nostalgic comfort food. Spanning eight different states, the historic route guarantees adventures from Chicago to California. Near St. Louis, visitors can marvel at the iconic Gateway Arch that has become synonymous with the city's skyline.

These quirky attractions have become legendary stops along America's Mother Road.

Some must-see roadside attractions include:

• The Blue Whale of Catoosa, Oklahoma – an 80-foot concrete whale you can actually walk through
• Cadillac Ranch in Amarillo, Texas – where 10 vintage Cadillacs stand nose-down in a field
• Elmer Long's Bottle Tree Ranch in California – a unique forest made entirely of bottle trees

You'll also discover historic treasures like the Chain of Rocks Bridge in St. Louis, with its distinctive 22-degree bend, and natural wonders like the 81-foot-deep Blue Hole in New Mexico.

The Legacy and Decline of America's Singing Road

When New Mexico's Department of Transportation partnered with National Geographic Channel in 2014, they created something magical – a quarter-mile stretch of singing pavement near Tijeras.

If you drove at exactly 45 mph, you'd hear "America the Beautiful" through your tires, creating a unique blend of musical nostalgia and road safety. The attraction drew visitors worldwide, becoming a cultural significance along Route 66. People would often make U-turns just to experience it again. The musical road was designed to help prevent accidents by encouraging drivers to maintain the ideal speed limit on this monotonous stretch.

Sadly, by 2020, this musical marvel began to fade. New asphalt layers and lack of maintenance have muffled the melody, and the guiding signs have disappeared. The engineering feat required 1,300 feet of road to be precisely grooved with rumble strips to create the musical notes.

While you can still drive over these rumble strips today, you won't hear the clear tune that once made this stretch of road famous. There aren't any plans to restore it due to high costs.
