[3] Segmental arches are known only from a limited number of Roman bridges, and came into widespread use not until the late medieval period (see e.g. Ponte Vecchio).

[3] The pavement of the roadway has completely disappeared, but the constant gradient of the ramp indicates that the ancient paving stones lay directly on the present-day surface.

[6] Circular ducts with a diameter of approximately 26 cm, which run through the length and width of the bridge, are interpreted as hollow forms of round construction timber of the Roman scaffolding and falsework.

[7] Although the surviving ramp does not allow to determine the number and type of the arches of the bridge proper, the ancient structure must have been a rather impressive engineering feat, judging from its current height of 8 m above the sediments and the 500 m wide river bed which needed to be spanned.

A possible starting point for the dating of the Seydikemer bridge provides a Roman road in the area which is known to have existed at the beginning of the 3rd century AD.
