Your final stop in Texas is Glenrio, which essentially straddles the Texas-New Mexico border, offering even more of the rustic gas stations, diners, and motels you've come to appreciate while traveling on Route 66. Although the town doesn't see many travelers these days, it still provides a great glimpse in the Mother Road's historic past, when thousands of travelers passed through Glenrio daily.
Keep an eye out for a former motel once featuring two names, depending on which way you were headed – the First Motel and Last Motel in Texas. Today, little remains except for the building's shell and parts of the sign, but these are interesting sights nonetheless.
Trivia: Glenrio was named in 1903; its name is a combination of Scottish "glen" and Spanish "rio."
Interstate 40 runs just north of the former Route 66 alignment. You can check out Glenrio by using Exit 1. To head into New Mexico, it's best to double back to I-40.
