Hence for the medium span in the range of about 35 to 60 m, a combination of supported span, cantilever and suspended span can be adopted and bridge with this type of superstructure is known as balanced cantilever bridge. But unyielding supports are required for continuous construction. If continuous spans are used, the governing bending moment can minimised and hence the individual span length can increase. Balanced cantilever bridges are used for special requirements like 1) Construction over traffic 2) Short lead time compared to steel 3) Use local labour and materials.
