Structure Types
General guidelines as below will be followed:
The structure should aesthetically blend with the environment.
The type and span arrangement will be such as to provide maximum riding comfort and involve minimum inspection and maintenance during the service life of structure.
Continuous superstructure with fewer number of bearings and expansion joints if not unsuitable otherwise will be preferred over simply supported spans.
For small bridges and culverts integral concept (in which sub-structures and superstructure are made joint less i.e. monolithic) is preferred.
