Detailed explanation-1: -The most recognizable feature of Roman aqueducts may be the bridges constructed using rounded stone arches. Some of these can still be seen today traversing European valleys.
Detailed explanation-2: -The arch allows the load to spread out instead of pushing straight down. The load spreads out to the abutments, which are supports on the ground at both ends, which keeps the ends of the arch bridge from breaking apart. The curved design and abutments allow the entire bridge to carry the load.
Detailed explanation-3: -They used arches which provided adequate support for the aqueducts. Arches were constructed by using wooden supports that created the curvature of the arch and were removed after the stone arch was constructed around it (Figure 2). The aqueduct was usually lines with concrete.
