Federal Highway 5 (Spanish: Carretera Federal 5, Fed. 5) is a tollfree part of the federal highways corridors (Spanish: los corredores carreteros federales), and follows the northeast length of the state of Baja California from the US-Mexico border in Mexicali at the northern point at San Felipe in the south. The highway is entirely inside the Mexicali Municipality. However, a state highway from San Felipe to Puertecitos (San Felipe Municipality) is usually considered part of Fed. 5. From San Felipe to the south, the road follows the seacoast of the Gulf of California.
