The Black (Pugh's Mill) Covered Bridge One of the longest and most impressive of Ohio's covered bridges, the Black (Pugh's Mill) Bridge was built in 1868-1869 by master builders Bandin, Butin, and Bowman. It is unique for its combination of two truss types - Childs and Long - within a single structure. Originally a cambered (arched) single span of 209 feet with a roadway width of 18 feet, it was modified in 1869 with the inclusion of a central pier under it for additional support. The trusses were then remodeled by replacing some of the wooden diagonals with iron rods to enable the builders to lower the bridge down onto the pier by backing off the nuts on the ends of the rods, thus elimination the camber and forming two spans instead of one.
