Guerrero Negro is the nearest community to the point where Fed. 1 meets the 28th parallel north. Afterward Fed. 1 leaves the western coast and crosses to the eastern coast at Santa Rosalía. The route continues southward past Puerto Escondido and gains altitude at Sierra de la Giganta, then veers southwest and through agricultural lands and Ciudad Constitución. After crossing a desert the route encounters La Paz on the eastern coast. The route continues along the gulf side of the peninsula through San José del Cabo to its terminus at Cabo San Lucas. After crossing state lines the kilometer markers progress in the opposite direction. Baja California signage count from north to south, but Baja California Sur signage count from south to north. So in opposite order from the road signage, a progressive route southward would span from Guerrero Negro to Santa Rosalía, from Santa Rosalía to Loreto, from Loreto to Ciudad Insurgentes, from Ciudad Insurgentes to La Paz, and from La Paz to Cabo San Lucas. This highway also goes under the Cross Border Xpress terminal in Tijuana.
