The sides of the Koca Çay river that flows through ancient Aizanoi used to be connected by four bridges in Roman times, two of which remain, this one seems the more famouis Penkalas Bridge. That is a Roman bridge across the Penkalas (Koca Çayı) in Aizanoi in the ancient region of Phrygia, modern-day Turkey.
Both have five arches and are still in use. Their tops look modern, but looking at the side you see antiquity in use.
I managed to miss two reliefs that were put on one bridge when it was opened for use in 157 AD.
