Nogales-Mariposa Port of Entry
The Nogales-Mariposa Arizona Port of Entry opened in 1973 to divert truck traffic away from the busy downtown Grand Avenue border crossing. It connects Arizona State Route 189 directly with Mexican Federal Highway 15. All commercial traffic entering the United States at Nogales now enters through the Mariposa port of entry. The port facilities are currently undergoing substantial renovation to accommodate increasing traffic and to support new equipment and procedures.
