What is the procedure for bridge design?

To determine the founding level at the site, it is necessary to carry out soil investigation.Return wall may be required depending on the span.

A bridge abutment is a structure which connects the deck of a bridge to the ground.Damage from the Earth pressure, the gravity loads of the bridge superstructure and abutment, live load on the superstructure or the approach fill, wind loads, and the transitional loads transferred through the connections between the superstructure and the abutment should be designed so as to survive.The most severe condition of loading should be investigated in combinations of those forces.
