Over the weekend, I crossed the border into northern Mexico. (In Chihuahua state, specifically.) Here is a 360-degree photograph from the small border town of Palomas:

This is Federal Route 2 leaving the international crossroads at New Mexico.
In Mexico, road-naming convention is unique. How so? One route number can contain several "branches". Imagine a mainline highway called Route 2. There's a spur off the road in a rural area. That spur is also known as Route 2 -- no other special title is given.

The following video shows Route 2 signage, via overhead gantry, near Palomas:

(This video was taken last year. Route 2 signage is best viewed during the first few seconds of the video.)
In all, Palomas is an interesting haven for those wishing to experience Mexican border towns w/o all the rush and crowds. It's a great place to visit in the spring before 40C temperatures arrive in the summer. To reach Palomas, take Interstate 10 into New Mexico and take a half-hour drive along southbound State Route 11 to reach the destination.
Cheers,
