The limestone was quarried not only for the bridge, but for other parts of the aqueduct towards Nimes, using picks and sharp metal corners. The quarry’s location could have made transportation of the limestone an easy task by using boats to ferry it on the Gardon river. Archaeologists have uncovered evidence on the bridge of numbering points for scaffolding, and evidence of the use of hoists to haul stone up the bridge, exhibiting the skillful engineering the Romans used in construction of the aqueduct. The bridge is constructed with huge blocks of cut stone, held together without the need for mortar except for the top tier of arches which is constructed out of breeze blocks held together by mortar, and crowned with a water channel coated with calcium for the transport of the
