Road vehicles including any load they are carrying should not exceed 5.03m (which is the normal minimum clearance under highway bridges in the UK).
Does height matter in a bridge?
The size of the beam, and in particular the height of the beam, controls the distance that the beam can span. By increasing the height of the beam, the beam has more material to dissipate the tension. To create very tall beams, bridge designers add supporting lattice work, or a truss, to the bridge’s beam.
