Re: niteroi bridge
President Costa e Silva Bridge, commonly known as the Rio-Niterói Bridge, is a box girder bridge crossing Guanabara Bay, in the State of Rio de Janeiro in Brazil. It connects the cities of Rio de Janeiro and Niterói. It is currently the longest prestressed concrete bridge in the southern hemisphere and 6th longest in the world. From its completion in 1974 until 1985 it was the world's second-longest bridge, second only to Lake Pontchartrain Causeway. The bridge was constructed by a Consortium of Brazilian companies led by Camargo Correa SA (for the concrete works) and by Cleveland Bridge & Engineering Company and Redpath Dorman Long in association with Montreal Engenharia of Brazil (for the steel navigation spans). It is 13.290 kilometres (8.258 mi) long – 8.836 kilometres (5.490 mi) over water and the bridge's 300-metre (980 ft) central span is 72 metres (236 ft) high in order to allow the passage of hundreds of ships entering and leaving the bay every month. It carries 140,000 vehicles daily, which pay a toll only when entering Niterói of R$5.50 (as of September 2014), about US$2.50 or €1.90. It has 18 access points and eight overpasses. Officially it is part of federal highway BR-101. From 1 June 1995 it was under the management of Ponte S.A. under a 20-year concession until 1 June 2015 since when Ecoponte has managed the bridge.
