Reinforced concrete box culverts are an economical design solution for many tunneling, drainage and short-span bridging requirements. In drainage structures, they can cope with large flows of water where headroom is limited. Hence they are ideal in road and rail structures where they are designed to take heavy wheel loads with no fill required above the structure. This provides instant bridging with minimum traffic disruption. The fact that traffic may use such an installation immediately after placing is noteworthy when compared with any insitu construction and most alternative materials which require compacted fill in place before the loading is applied.
