The Durango-Mazatlan Highway is one of Mexico's greatest engineering feats, 115 bridges and 61 tunnels designed to bring people, cargo and legitimate commerce safely through a mountain range known until now for marijuana, opium poppies and an accident-prone road called the Devil's Backbone.
Even those protesting the project say the 230-kilometer-long (140-mile) highway, expected to be completed in August, will change northern Mexico dramatically for the good.
It will link port cities on the Gulf of Mexico and the Pacific by a mere 12-hour drive, and Mazatlan with San Antonio, Texas, in about the same time.
The highway will eventually move 5 million vehicles a year, more than four times the number on the old road, plus more produce and goods from Asia to the Mexican interior and southern U.S. Sinaloa state tourism officials predict an "explosion" for the resort city of Mazatlan, hard hit by drug violence in recent years, as the new road gives 40 million Mexicans in interior states an easy drive to the beach.
"It will change the landscape of this part of the country," said Tourism Secretary Francisco Cordova. "It's an opportunity to develop these areas and diversify the local economy."
But it remains to be seen if the $2.2 billion highway will pull the towns of wood and corrugated-metal shacks in rural Sinaloa and Durango away from their historical ties to drug trafficking.
