Structure The original shape and construction of the Roman-era bridge have been reconstructed digitally, based on the extant remains of the ancient structure: the ramps, the
abutments, and foundations of the piers. Several pieces of the original bridge are scattered along the river bed on both banks, and were not used during reconstruction. It crossed the river at a basic 90-degree angle, although it bent slightly on one end. This middle section stood on six arches, while both sides had smaller arches (one on the right and two on the left) which served as
spillways in case the river overflowed. At its normal level, the river flowed between the three central arches, constrained by double-wedge-shaped reinforcements of masonry, placed at the two outer pillars and intended to prevent their undermining by the river. The main body of the bridge was built using
concrete, which survives in at least one Seljuq-era pier as a foundation.
Dates aqueduct The exact date of the bridge's construction is uncertain. The date of construction is closely connected with the
Aqueduct of
Aspendos, parts of which were re-used in the bridge. In the outer shell of the bridge alone, 250 pipe-shaped stones from the aqueduct's main pressure conduit were re-used. == Seljuq bridge ==
