Carretera El Espinazo del Diablo

Carretera El Espinazo del Diablo — The Devil’s Backbone Highway — earns its menacing name through 50 kilometers of white-knuckle driving along knife-edge ridges between Mazatlán and Durango. This legendary stretch of Highway 40D clings to mountain faces with drops exceeding 1,000 meters, threading through tunnels blasted from solid rock and across bridges that span impossible chasms. The road reaches its terrifying apex at the Baluarte Bridge, the highest cable-stayed bridge in the world at 403 meters above the Baluarte River canyon.

Despite being paved highway, this route demands respect and experience with mountain driving — fog, rain, and rockslides are constant threats. Heavy vehicles and trailers face serious challenges on the steep grades and tight corners. Travel during daylight only and check weather conditions; winter can bring ice at higher elevations. While technically accessible to any vehicle, the psychological challenge and spectacular engineering make this one of Mexico’s most memorable drives, offering views that’ll haunt your dreams long after you’ve safely reached Durango.
