Federal Highway 15 (Spanish: Carretera Federal 15, Fed. 15 ) is Mexico 15 International Highway or Mexico-Nogales Highway, is a primary north-south highway, and is a free part of the federal highways corridors (Spanish: corredores carreteros federales) of Mexico. The highway begins in the north at the Mexico–United States border at the Nogales Port of Entry in Nogales, Sonora, and terminates to the south in Mexico City. Fed. 15 from Nogales to Mazatlán runs parallel to Fed. 15D, a tolled (cuota) part of the federal highways corridors (los corredores carreteros federales); the portion of this northern stretch from the town of Eldorado southward within the Sinaloa is a limited-access highway. North of the U.S.-Mexico border, the highway continues to the north from the Port of Entry, as I-19 Business. The highway is the southern terminus of the CANAMEX Corridor,[citation needed] a trade corridor that stretches from Mexico north across the United States to the Canadian province of Alberta.
