Justinianus Köprüsü
51.2 km · The Sangarius Bridge or Bridge of Justinian is a late Roman bridge over the river Sakarya in Anatolia, in modern-day Turkey. It was built by the East Roman Emperor Justinian I (527–565 AD) to improve communications between the capital Constantinople and the eastern provinces of his empire. With a remarkable length of 430 m, the bridge was mentioned by several contemporary writers, and has been associated with a supposed project, first proposed by Pliny the Younger to Emperor Trajan, to construct a navigable canal that would bypass the Bosporus.
