The new Bassein Creek Bridge, located on National Highway NH8, one of the main arterial routes north out of Bombay, is an eight span balanced cantilever structure. It crosses an inlet from the Arabian Sea which, at its crossing point, is about a half kilometre wide and which has swift flowing currents and a tidal range of 4 metres. In addition, it is located in a seismic zone with recent recorded activity.

The foundation design is of the traditional well type caisson construction. However, during the design stage it was found that, if the seismic load was to be carried in the configuration required, an unacceptably large caisson construction would be required mid-stream. This raised not only questions of cost but also the feasibility of the construction on the scale envisaged would have been extremely difficult.

To overcome the problem but at the same time maintaining the general design and appearance of the superstructure, the design consultants elected to use LUDs on the two piers adjacent to the central support. By redistributing the seismic load, the designers were able to reduce the size of the caisson foundations of the middle pier by some 50%, which produced a considerable saving on the caisson of more than 30 metres depth.

The units were installed in 2001 shortly before the completion of the bridge, being fitted without difficulty to anchor plates previously cast into the structure, and represent the first use of Lock-Up Devices anywhere in India.
