Twelve years after it was started, and after the construction of 166 bridges plus viaducts and more than 11 underground miles in 61 tunnels, the 140-mile-long Mazatlan to Durango Highway opened this week. It is the biggest single public works project undertaken in Mexico this century. The Baluarte Bridge, 3,688 feet over the valley floor, is the highest of its kind in the world. Although not built with tourism in mind, the road now makes possible day trips from the port to legendary, Brigadoon-like Durango, least-visited state capital in the country. Isolated by ore-rich mountains, Durango is the town the Colorado ski resort is named for.
