[1] The Greek geographer Strabo (63 BC–AD 21), who lived in Nysa, mentioned a secret water conduit in the town, but it remains unclear whether he meant the existing tunnel-like bridge.

[2] An inscription at the northern wall of the tube, close to a bend after 25 m (82 ft), indicates a construction date in late imperial times.

[4] The Nysa Bridge served as a substructure for the area in front of the city theatre, which lay close to the Cakircak stream.

[2] The capacity limit of the Nysa Bridge in case of floods has been the subject of hydraulic and hydrological research.

Considering that the Cakircak is 6 km (3.7 mi) long, with a median gradient of 19% and a drainage basin of 4 km2 (1.5 sq mi), the following median intervals were calculated, depending on the method employed: The study came to the conclusion that statistically every 13,500 years, a value which has been referred to as the "arithmetic mean", floods are to be expected which would exceed the capacity of the bridge.
