Little Gap Covered Bridge in Carbon County, Pennsylvania #336932779
Description

Built between 1840 and 1860, builder and exact date of construction unknown, the combined Howe truss and Burr arch construction system was very sophisticated for its time and is a precursor to iron bridge and steel bridge technology. The iron tie rods were probably original and would have allowed construction to be completed rapidly with green lumber.
