Nogales Mariposa
6AM - 10PM Daily
Mariposa is the modern crossing west of downtown Nogales, with good height clearance and space for big rigs. Southbound traffic is often waved through; complete your vehicle paperwork about 21 km south, not at the line. The main concern here is the security situation in Nogales, Sonora, so cross during daylight.
