WebBridges. Precast concrete is commonly used in the construction of highway, rail and pedestrian / cycleway bridges for its durability, high quality and low maintenance. Standard sections use a range of spans from 7m to 40m … WebSingle box girder is cast in-situ if the bridge has a span of 30m – 250m Below the 30m span of the bridge, the decks with void for precast concreting are preferred. And over 50m, a single trapezoidal box bridge is more economical. The top and bottom of flange thickness should not be less than 1/30 of the clear span between webs.
