Bandra Worli Sea Link
Project description
Forming a much needed new link between the island city of Mumbai and its populous western suburbs, the 5.6 km long Bandra Worli Sea Link includes the 600 m long single tower cable stayed Bandra Bridge with 250 m main spans and the 350 m long Worli Bridge, also with a single central tower and main cable stayed spans of 150 m. Eight lanes of traffic, including two dedicated bus lanes, run on the twin precast concrete box girder bridge decks. High strength concrete containing microsilica slurry is used throughout. Foundations for the main towers are 2 m diameter drilled shafts 25 m deep.
Mumbai and its suburbs have a total population approaching 13M, making it the second most populous conurbation in the world after Shanghai. The new crossing will relieve traffic pressures on the highly congested Mahin Causeway, where it can take peak hour commuters 40 minutes to cover the 8km of causeway.
mageba scope
No less than 26 TENSA-MODULAR expansion joints were needed for this project, ranging from the LR2 version up to the LR6 with a maximum capacity of 480 mm longitudinal movement. In addition, 126 RESTON-DISC disc bearings (Vmax = 14,000 kN) and hundreds of elastomeric bearings where supplied for this extraordinary bridge structure.
