This bridge carries the roadway out over the edge of a cliff along the river. Bridges performing this function are sometimes called a half-viaduct, although with this bridge, the entire width of the roadway is carried out over the cliff on the bridge structure, which is not always the case with a half-viaduct, as the name implies.
