Immediately below the Tahirid Harim the Upper Bridge of Boats crossed the Tigris, to which led the highroad from the Syrian Gate of the City of Mansur, passing through the Harbiyah Quarter diagonally. The Abu-l-jawn Bridge in all probability was on the Dujayl road, near where it joined the highroad which ran direct from the Syrian Gate up into the Harbiyah Quarter. The Dujayl Road Canal, after traversing these various Persian fiefs, turned off at right angles, flowing down towards the Syrian Gate, and first passed under the bridge called the Kantarah-Abu-l-Jawn. Some of the ancient palm-trees of the village were still growing here at the close of the second century in the reign of Amin; and from the author of the Marasid we learn that the Khattabiyah had stood on the bank of the Little Sarat, near where the Ram and Lion Quarter, with the tomb of Ibrahim-al-Harbi, afterwards came to be built.
