Bridge B, some upper trusswork. In this image, the largest beam is one of the main truss beams, the beam dropping to the lower right is a vertical truss (w/ lattice) and the two trusses (w/ lattice) going from right to left are cross members which are several feet between eachother on the vertical members.
