Eurymedon Bridge (Aspendos)

The foundations and other stone blocks (spolia) of the Roman structure were used by the Seljuqs to build a replacement bridge in the 13th century, the Köprüpazar Köprüsü, which stands to this day.

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.

The great height of the ancient structure is further verified by the discovery of 1.5 m long iron threaded rods, which, bound together with hooks and loops, were used to reinforce the masonry in the bridge's foundations.

[8] In the early 13th century, the Seljuq Sultan Kayqubad I (1219–1237) built a new bridge over the remains of the late antique structure,[9] which had collapsed, probably also because of an earthquake.

[10] This zigzag course, formed by two successive, 90 degree bends, in combination with the pointed arches give the Seljuq-era bridge an appearance that is quite distinct from that of its Roman precursor.
