S Bridge

S Bridge is the English-language name for a bridge over a body of water, the floor plan of which is curved in an S-shape.
The S-shaped construction is known from Ohio in the early 19th century. This type of construction was chosen to adapt the bridges to narrow and winding river courses in uneven terrain. The bridges start vertically on both banks and are brought together in the middle so that the river can flow vertically through the structure and the bridge represents a minimal barrier in the river. Some of these bridges have been preserved along US Highway 40 in Ohio and some are classified as National Historic Landmarks . The Claysville S Bridge in Washington County (Pennsylvania) is in the National Register of Historic Places out.
