Federal Highway 40, (Carretera Federal, Fed. 40) also called the Carretera Interoceánica (Interoceanic Highway), is a road beginning at Reynosa, Tamaulipas, just west of the Port of Brownsville, Texas, and ending at Fed. 15 in Villa Unión, Sinaloa, near Mazatlán and the Pacific coast. It is called Interoceanic as, once finished, the cities of Matamoros, Tamaulipas, on the Gulf of Mexico and Mazatlán on the Pacific Ocean will be linked.

It passes through Monterrey, Nuevo León; Saltillo, Coahuila; Torreón; Gómez Palacio and Durango City. The Monterrey to Durango City section is a four-lane divided highway. The rest of the road is a two-lane undivided road.^{[citation needed]} Parallel to this highway, in some sections, runs Fed. 40D, a four-lane restricted-access toll road.

The Cadereyta Jiménez massacre occurred on 13 May 2012 along the road outside the city of Monterrey.^[6]
