The structural evaluation consisted of measuring the length, width and height of the selected bridges, the functional ones, represented by the planialtimetric and runway characteristics, and durability, in which the nonconformity records were analyzed. Considering all the highlighted aspects, the classification of the construction condition was performed. As for the structural evaluation, an average of 10 m, 5 m and 2.45 m was obtained, for length, width and height of the piles, respectively, in the functional and durability characteristics, the standardization of some characteristics such as the number of strip, width of the wheel guard, among others, and the absence of signaling and catadioptric.
