Bridges are structures being used to cross rivers, lakes or any other obstacles which involve water. These instruments are commonly used in cities like Recife, which consists of several islands. However, it is common in this city to observe the fast deterioration of these structures that have been built for decades and are subjected to structural recoveries only when they present a possible imminent collapse. The maintenance of these constructions, often used as tourist spots, is essential because of the economic importance, while these structures are responsible for transporting people and cargo, and also play a key role in the city＇s roads. This paper aims to present and assess the conservation status of these bridges through the study of possible pathologies found at Princesa Isabel Bridge, Government Agamenon Bridge, Ponte Giratória Bridge and Paulo Guerra Bridge. The methodology for its inspection will be prescribed by ABNT NBR-9452/86, which provides for ＂Surveys of Concrete Bridges/Viaducts＂. After analysis, it was found that most bridges problems were caused by the presence of moisture that accumulates in bridges due to the absence or malfunction of drainage systems.
