Vashi Bridge
Encyclopedia
The Vashi Bridge, is a bridge
, built across the Thane Creek
that connects the city of Mumbai
to the India
n mainland at Navi Mumbai
. The bridge links the suburb of Mankhurd
in Mumbai with Vashi
in Navi Mumbai, the satellite city of Mumbai. The bridge of 1837m length and having a substandard 3 lane carriageway, is one of the four entry points into Mumbai, and handles traffic directed towards the regions to the south and east of Mumbai. The modern bridge was built in the 1970s. Within two years of its opening (which was in 1972) to traffic, corrosion cracks were noted on the bottom side of the prestressed girders of some spans. This led to a series of extensive repairs including external prestressing. It was simultaneously decided to construct a new bridge of 6 lane divided carriageway of 1837.35 m length, 30 m down stream, with emphasis on durability. This new bridge, called the 2nd Thane creek Bridge, was constructed from 1987 to 1997 with several unique features in the construction and design with emphasis on durability and a formal QA/QC programme. Proof Consultants were appointed to oversee each aspect of planning, design and construction. Open foundations were taken into the bedrock with foundation concrete being laid in the dry, with the sea water being pumped out using submersible pumps. The piers in the intertidal zone were protected by epoxy coal tar paint painted on 6 mm thick m.s. plate which was considered as a lost shuttering. The superstructure was a P.S.C. box girder, one for each carriageway, constructed using balanced cantilever cast-in-situ segments. The New Bridge called 2nd Thane Creek Bridge (also the Vashi Bridge) has performed without any problems whatsoever. This bridge was constructed by U.P State Bridge Corporation Ltd. http://bridgecorporationltd.com/awards.html for which it was awarded the most outstanding concrete structure award.
