Kramer Covered Bridge No. 113 is a historic wooden covered bridge in Greenwood Township, Columbia County, Pennsylvania, carrying a road over Mud Run. Built in 1881 as a 50-foot Queen Post Truss, it reflects practical late-19th-century rural bridge-building traditions, while its metal roof represents a later effort to protect the timber. Listed on the National Register of Historic Places in 1979, it holds value within Pennsylvania’s surviving covered-bridge landscape. Rebuilt in 2007, it continues to serve as a maintained historic crossing and remains part of the notably dense regional collection of preserved covered bridges in the Columbia and Montour county area.
