What materials were used to construct the Bridge?

The chains and suspension rods are made of wrought iron.

The piers (towers) are built principally of local Pennant stone. The Leigh Woods (south) pier stands on an abutment of red sandstone. The Bridge deck is made of timber sleepers, 5 inches (12 cm) thick overlaid by planking 2 inches (5 cm) thick. Since 1897 the deck has been covered with asphalt.
