Battling floods, difficult soils and the environmentally sensitive nature of the Amazon rainforest, crews are building a 3,600-meter-long, $400-million bridge with a 400-m-long cable-stayed central section over the Negro River using a 400-barge working platform. The project, marked by a death and environmental controversy, is intended to boost economic development in the Amazon. Brazil’s Manaus-Iranduba Bridge, scheduled for completion by year’s end, will straddle the river close to where the waterway merges with the Amazon River. The span will create a land link between the city of Manaus and the town of Iranduba as well as 30 other, smaller municipalities.
