Nogales-Grand Avenue Port of Entry

The Nogales Arizona Port of Entry on Grand Avenue has been in existence since the early 20th century. It connects Interstate 19 with Mexican Federal Highway 15. The port of entry is named after former Arizona Senator Dennis DeConcini. The border station was completely rebuilt in 1966 and upgrades to the pedestrian gates were made by the General Services Administration in 2012. It is one of three border crossings in Nogales; the Nogales-Mariposa Port of Entry, built in 1973, handles commercial traffic west of the Grand Avenue crossing, while the adjacent Nogales-Morley Gate Port of Entry is used for pedestrians.

Morley Gate is dedicated to pedestrian crossings. The Grand Avenue garita was expanded substantially in 1949, but was replaced with the current multi-lane inspection facility in 1966.
