The Bavian-Khazir canal included an aqueduct of concrete and stone to crossed over a deep wadi (seasonal streambed). Located near Jerwan village, the ruins are called the Jerwan aqueduct. The aqueduct is over 9m tall, 22m wide, and 280m long. It used 2 million stone blocks, each averaging 50x50x65cm. This type of monumental structure is unknown elsewhere before Roman times.
