 The bridge surface is located only 30 – 40 cm (11.8 – 15.7 in) over the arches' apex, is 3.55 – 3.70 m (11.6 – 12.1 ft) wide, increasing towards either end at 4.30 m (14.1 ft) and projects ca. 10 cm (3.9 in) over the superstructure on either side. It is paved with large and irregular limestone cobblestones, although smaller pebbles have been used in the repairs at the two semicircular arches.
