Furnace Covered Bridge No. 11 is a historic wooden covered bridge in Cleveland Township, Columbia County, Pennsylvania. Built in 1882, it carries a road over the North Branch of Roaring Creek on a 100.9-foot Queen Post Truss span. Its tarred metal roof was a practical feature that helped shield the timber structure from weather. The bridge is part of a notable concentration of surviving covered bridges in Columbia and Montour Counties, where 28 historic examples remain. Listed on the National Register of Historic Places in 1979, it continues to serve road traffic while reflecting the region’s 19th-century bridge-building traditions.
