The Road That Connected a Peninsula: How Baja California Sur Became a State in 1974

It is easy to forget, sitting on a terrace in Los Cabos, that this corner of Mexico was once remote in a way that is hard to imagine. For much of the twentieth century, Baja California Sur was a federal territory, not a state, reachable mostly by sea or by rough desert tracks.

The turning point came in 1973. The Transpeninsular Highway, connecting Tijuana at the U.S. border with Cabo San Lucas at the southern tip, was completed, and it was formally opened on December 1, 1973, near Guerrero Negro by President Luis Echeverría. For the first time, you could drive the full length of the peninsula on paved road.

From Territory to State

The territory of Baja California Sur had existed since 1931, and the peninsula had been divided into two federal districts as far back as 1887. On October 8, 1974, the year after the highway opened, Baja California Sur became a state, alongside Quintana Roo, making them the newest states in Mexico. Historians debate how directly the road caused statehood, but the timing tells its own story: a region newly connected to the rest of the country was ready to govern itself.

Drive the Road Today

The same highway now runs past the airport, the marinas and the golf courses of Los Cabos. Today it is the easiest way to reach Cerritos on the Pacific and San José del Cabo on the Sea of Cortez, and a private driver arranged by our concierge turns it into a scenic part of the trip rather than a chore.
