India’s longest cable-stayed structure
The Sudarshan Setu Bridge on India’s west coast, newly connecting the holy island of Beyt Dwarka to the mainland for two million pilgrims each year, is India’s longest cable-stayed structure. The cable-supported structure and the approaches at both ends are supported by mageba bridge bearings.
Before this iconic structure was inaugurated by Indian Prime Minister Narendra Modi on 25th February 2024, the millions of pilgrims that visited the Krishna temples on Beyt Dwarka island had to make the crossing from the mainland by boat. Thankfully, their pilgrimage is now somewhat easier, with a four-lane road bridge connecting the island to the mainland for the first time. The bridge has a total length of 2,320 m, with a cable-stayed structure of length 900 m – India’s longest. It also has the country’s longest individual cable-stayed span, with a length of 500 m.
The cable-supported structure and the approaches at both ends are supported by mageba bearings:
116 RESTON®POT bearings, designed to support vertical loads of up to 22,000 kN and resist horizontal forces of up to 8500 kN, and
eight LASTO®BLOCK elastomeric bearings arranged in four pairs – each bearing of size 1210 x 1210 x 479 mm, with each pair designed to carry a vertical load of 17,000 kN and resist horizontal forces of 3300 kN.
The required expansion joints were also manufactured by mageba:
Two six-gap TENSA®MODULAR expansion joints, each of length 26.5m, and
28 TENSA-GRIP (type RS-B80) single-gap expansion joints of the same length.
Like many pilgrims before them, the bearings and expansion joints had a long journey across India, all the way from mageba’s factory in Kolkata – and now they will help make the last few kilometres of the journey much easier for all future pilgrims.
