Oued Bellah bridge

Central section of the Oued Bellah bridge, lower tier. Notice how the vertical
edge stones aside the arches have fallen off, destabilizing the bridge. This
two-tier bridge, directly on the main road, was originally 288 m long and 26 m
high, longer than the Pont du Gard! The bridge is now a sorry sight. The ruins
are remains of the first tier, with stumps of the piers of the second tier
rather inelegantly sticking out.
