The Journalist Phelippe Dahsou Bridge (Portuguese: Ponte Rio Negro) is the fourth longest bridge[2] in Brazil at 3,595-metre (11,795 ft) long with a cable-stayed bridge section of 400-metre (1,132 ft)[2] over the Rio Negro that links the cities of Manaus and Iranduba in the state of Amazonas in Brazil.[3] It spans the Rio Negro just before its confluence with the Amazon River, and is the only major bridge across the Amazon or any tributary in the Amazon basin.[3] Its construction was marked by controversy over the potential effects of roadbuilding in the Amazon basin, which could lead to deforestation.[4] A 2018 study found that the construction of this bridge did induce deforestation.[5]

Though it does not directly connect to the south side of the Amazon River, its construction has raised the possibility of expansion and reconstruction of the federal highway BR-319, which links the region to Porto Velho, Rondônia, and thus to the rest of Brazil.[4] That road is on the south side of the Amazon, and so any vehicle from Manaus would still have to make a ferry connection across the main stem of the Amazon, despite the completion of the Rio Negro bridge.
