On Kozlu Bridge connects the two sides of the Tigris with blocks built on ten cut arches. From the floral kufic inscription with two lines on the southern facade - between the arches and the balustrade - it is understood that it was built by an architect named Ubeyd between 1064-1065 by the Ebol qadi al-Hasan Abd al-Wahed; However, scholars agree that this inscription is a restoration inscription and the work is said to have been done at a much earlier date.
