The effort to build the longest bridge in Peru began in 1978, and, if all goes as planned, the 722-meter-long span over the Madre de Dios River in the Peruvian Amazon will be completed in December.
Constructing the Guillermo Billinghurst Bridge—a task spanning more than three decades—will cap the effort to build a paved road in South America from the Atlantic Ocean to the Pacific Ocean: the Interoceanic Highway. The $2.37-billion project to build the road across southern Peru was expanded last year to include the long-awaited span.
