The glory days of U.S. Route 66 may be in the rearview, but its legacy continues to grow at stalwart roadside outposts like the Heart of Route 66 Auto Museum, which is almost finished building a (potentially) record-breaking oddity.

The museum recently added the crowning medallion to a giant novelty gas pump, which, they say, is the tallest in the world, according to KTUL. Like so many over-sized installations before it, the world’s tallest gas pump—in total, 66-feet tall, of course—is being installed in front of the museum not just as an homage to the road’s history of kitsch, but as a beacon to passing travelers, hopefully luring them in for a visit.

The illuminated top-piece alone measures an impressive 14-feet tall; crews completed its installation Friday.

“This is by far the craziest thing I’ve ever decided to build, but it’s worth it,” Clint Oare, who built parts of the pump, told KTUL.

Once it is complete, museum officials plan to have it checked by the Guinness World Records to make its title official. Until then, the sign will just stand as another in a historic tradition of giant things off the Mother Road.
