Kidd's Mill Covered Bridge
Built in 1868 to replace a span destroyed by flooding along the Shenango River, the Kidd's Mills Covered Bridge is the last remaining historic covered bridge located in Mercer County, Pennsylvania. Known in Mercer County's inventory as Bridge # 1801, the bridge is located on Township Road 471, about a half mile east of PA 18, near the community of Transfer in Pymatuning Township. The 124 foot long covered bridge was designed using a Smith through truss design and is the easternmost covered bridge that utilizes the Smith through truss design. The bridge was built by the Smith Bridge Company of Tipp City, Ohio (formerly known as Tippecanoe City). The Smith truss design for a covered bridge was kind of like the bridge version of a Craftsman home, as it was not constructed on site. Devised and patented in 1867 by Robert Smith, both the tension and compression members were all wood. During the period of 1867 to 1870, Smith built fifteen of these patented structures in Miami Cou
