The grandfather of bridges, authentically duplicated in plastic. This Truss Bridge is the most common steel bridge found in North America, if not the world, and fits both steam and diesel eras. Can be easily modified in length or width to fit all your needs. The importance of this bridge design was that greater distances could be spanned, resulting in less supports. A river or gorge can be crossed with fewer piers while still supporting sizeable loads. Approx. 5″ H x 2-3/4″ W x 15″ L
