The Metropolitan Region of Recife-PE is among the capitals where transit is considered one of the most congested in the country and some works are extremely important so that bottling does not grow. The walkways, which are Works of Special Arts, allow this fluidity, avoiding stops or interruptions for pedestrian crossings, as well as ensuring their safety. The lack of maintenance can jeopardize this guarantee, because what was observed with this study is a state of abandonment of these structures that are very important. The objective of this study was to study the pathological manifestations found in the catwalks of the Metropolitan Region of Recife. It was observed that they are several manifestations, but the corrosion of armor is very striking mainly in the catwalk of the Engenho do Meio that presents, in some pillars, the armature completely exposed with loss of section or steel ruptured. In Paratibe the walkways are of the stationary type, a real work of art, but the lack of care is so evident that one of the support cables of the structure is already broken and the other cables present a well advanced state of corrosion. Finally, the study carried out in these structures shows the importance of periodic surveys that can be one of the tools to indicate the places where immediate intervention is necessary, avoiding a high maintenance cost with the interruption of the use or demolition of these Works of Arts Specials.
