The Rio–Niterói Bridge, officially the President Costa e Silva Bridge, is a box girder bridge spanning the Guanabara Bay, connecting the cities of Rio de Janeiro and Niterói in the State of Rio de Janeiro, Brazil. It is currently the second longest bridge in Latin America, after the Metro Line 1 bridge, and the 48th longest in the world in 2020. From its completion in 1974 until 1985 it was the world's second-longest bridge, second only to the Lake Pontchartrain Causeway.
