Nysa Bridge

The Nysa Bridge is a late imperial Roman bridge over the Cakircak stream in Nysa in the ancient region of Caria [1]. The 100 m long substructure was the second largest of its kind in antiquity, after the Pergamon Bridge [1]. The Nysa Bridge served as a substructure for the area in front of the city theatre [1]. It was built as a two-level structure: the bottom vault spanned the brook [1]. On top of it a row of arches connected the two hills that formed the urban area [1]. The ground arch spanned the stream on a length of some 100 m, giving the bridge the appearance of a tube or a tunnel, although it was constructed entirely above ground [1]. It consists of a single, 5.7 m wide vault whose uphill mouth widens to 7 m [1].
