Bridges are meant to cross a natural obstacle like stream, valley, rivers and etc. They are subject to actions that cause the appearance of deformations in the structures and thus, maintenance is required to maintain the current state of the work. In addition, the lack of maintenance reduces the useful life of Special Artworks (OAEs) and in most cases the structure is abandoned. In this context, this work has as its main objective. This work aims to detect the anomalies in the Tocantins Bridge over Porto Nacional, located at TO - 255 through visual inspection and photographic records using UAV (Unmanned Aerial Vehicle). The inspections followed the guidelines of NBR 9452 (2016) and the Road Bridges Inspection Manual (DNIT, 2004). Finally, it was found that the bridge, according to the condition classification criterion of special art works of NBR 9452 (2016), presents a critical condition, which requires immediate intervention.
