El espinazo del diablo (The devils backbone) is a mountain pass located in Durango, Mexico, famous for its hairpins and zigzags turns. The road links Durango and Mazatlan Sinaloa.
El Espinazo del Diablo (The Devil’s Backbone) it is located at kilometer 168 of the Highway 40 and covers a stretch of highway about 10 km, where you can see the wonderful spectacle of the Sierra Madre Occidental. This section of the highway is narrow with lots of curves (around 2.000). Despite of many cautionary tales about crossing the devils backbone, El Espinazo Del Diablo, is exceptionally well maintained and there are many cautionary signs marking most of the hazards. There are some tight curves, too. So tight that a truck needs all of the road to make it around.
During the winter months there is the added danger of ice. The road passes through mountains and deep ravines. The construction of this road was a hard job in some sections: one sidehas big banks and the other cliffs. If we add that is one of the routes with more assaults, robberies and even murders, it becomes one of the most dangerous roads. The road runs across dozens of deep ravines. Bends with a bumpy asphalt and rocks bordering at 2.000 higher. At afternoon is usually covered in a thick fog that traps less cautious drivers, turning every curve and narrow way into an odyssey.
Anyways, the project of a new road, that began 15 years ago, will turn this infamous road into a safe trade route. The highway project, of 140-miles-long, has 115 bridges and 61 tunnels and will cost $2.2 billion. The new highway will move 5 million vehicles a year—four times the number handled by the old road.
