Construction of Culverts and Small Road Bridges Across Drains and Canals* 15.1. Introduction Whenever a new road has to cross an existing drain or a canal, or sometimes, when a' drain has to cross an existing roa<;i ; a small bridge or a culvert** is constructed at the point of crossing.
New bridges are assumed to be constructed at the same location of the existing bridge when the new road is located on the existing road. In case that a new bridge is constructed at the same location as an existing one, the construction sequence is described below.
simplest road alignment and the preferred bridge site. For a river crossing, the cheapest bridge site and the one that has the longest potential service life is that
ORN9: A guide to small bridge design for highway engineers
Guidelines for the planning stage, through site investigations, materials analysis, hydraulic design and structural design. Small bridges and culverts are an essential part of every road...
Short-span bridges – bridges that have a length between end supports not more than 30 m. They can have one or multiple spans. Situation – particular set of conditions, circumstances and constraints. It is based on evaluation of the current state and possibilities (economical, geographic, climate, social).

The Bureau of Bridge Design has assembled Bridge Sample Plans and Bridge Plan Checklists that can be used as an aide in the preparation of detail construction plans for bridges.

As a result of the study, the basic plan of two bridges was proposed as shown in Table-1 and Table-2. Table-1 Basic Plan (Bazal Bridge) Bridge Type 4-span PC-I Girder Bridge
General: Occurrence of culverts and small bridges on roads and highways depends upon the type of region and terrain. The location, size and other details of such structures should be decided judiciously to cater for the requirements of discharge and balancing of water level on either side of road embankment.
