Stone Bridge is a Roman bridge spanning the Seyhan River in Adana that was probably built in the first half of the second century AD. The bridge was a key link in ancient trade routes from the Mediterranean Sea to Anatolia and Persia. Until its closure in 2007, it was one of the oldest bridges in the world open to motorized vehicles. Since 2007 it has only carried foot traffic, and now hosts social and cultural events. Among the names used for the bridge during its history are the Saros Bridge, the Bridge of Justinian, the al-Walid Bridge and Taşköprü ("Stone Bridge" in Turkish).
