It is of rugged construction with naturally grown ribs, thick crossbeams and a solid gunwale. Some of these transmission masts are linked to each other by crossbeams furnished with catwalks. The crossbeams contain Roman portrait heads, while the cornice contains generic sculpted grotesques. The interior was constructed around four large pillars, upon which crossbeams supported the roof. The "odachi" style has rafters, crossbeams and short vertical posts to support the ridge. Added strength was provided by crossbeams and braces throughout the length of the hull. The cross has three horizontal crossbeams, with the lowest one slanted. The deck of the bridge was formed of cast iron crossbeams. These crossbeams may have been added in the extensive 1817 repairs.
