 The span of its single arch is 6.73 m, with a rise of 3.10 m, resulting in a slightly less pronounced profile (c. 160°) than the typical Roman semi-circular arch (180°); the overall height from the riverbed to the apex of the arch is reported as 3.60 m.

The vault was made of three parallel, transversal arches standing at intervals of 1.20 m; the arches were built of 60 cm long, 30 cm wide and just as high ashlar, while the spaces in between are covered with longish basalt blocks.This design principle – transversal arches with lintels – seems to be unique among Roman bridges.It also appears in the Hauran in roof constructions of late antique basilicas, and the early Christian church in Nimreh, indicating a construction date in the 3rd or 4th century AD.
