Turkey - The Bridge of Justinian

The Bridge of Justinian, also known as the Sangarius Bridge, is a late Roman bridge with a remarkable length of 350 m, constructed to span the Sangarius River in the ancient region of Bithynia in northwestern Anatolia. The bridge is located in the Beskopru neighbourhood within the Serdivan district, ca 5 km southwest of the town of Adapazari in northwestern Turkey. Today, the bridge spans the smaller Cark Deresi stream (called the Melas stream in Antiquity), which drains the nearby Lake Sapanca, whereas the modern course of the Sangarius currently lies 3 km to the East. It was built by the East Roman Emperor Justinian I (527-565 AD) to ameliorate the transportation and communication between the capital Constantinople and the eastern provinces.
