This new bridge type, wooden with a covered span, was developed because traditional European methods, typically stone bridges, were not appropriate for the harsh Pennsylvania winters. Many of the bridges were named for pioneer families residing near the bridges. [2] Some people call Pennsylvania the "Covered Bridge Capital of the Nation". [2]
The bridge's chain cables were carried over paired A-frame wooden towers on its east and west abutments, and a third pair of towers atop a stone pier built in the river. Its chains were made of 1.5-inch-square (3.8 cm) iron bar wrought into links of between 8 and 12 feet (2.44 and 3.66 m) in length.
