Masonry Arch Bridge Construction Fill often consisted of materials excavated during the building of the foundations. It may nevertheless have high strength as a result of its composition and compaction over the years. A waterproofing layer may have been laid on top of the fill and below the road surface, perhaps tar or puddled clay. The designer occasionally felt it necessary for stability to reduce the weight of the fill near the springings and buit in cylindrical opening passing completely throughout the structure. These openings also provide for floodwater. These are examples of roman bridges built with such openings. A famous example of the technique is the bridge at Pontypridd (1755) where its predecessors, similar in most other respects, collapsed shortly after removal of the centring by the weight of the haunches forcing the crown upwards.
