S Bridge was a historic stone arch bridge located at Marion Township in Berks County, Pennsylvania. It was a multiple span 230-foot-long (70 m), stone arch bridge with three spans, constructed in 1919. It crossed Tulpehocken Creek. It was listed on the National Register of Historic Places in 1988. In 2001, the bridge was closed when one of the bridge walls began to separate from an arch. After a decade of disuse, it was demolished and replaced with a concrete span in 2011.
