Zetwerk on a subcontract from Larsen & Toubro – IHI Infrastructure Systems last week completed trial assembly on a 130 meter long open web girder (OWG) bridge for the 508.17 km Mumbai – Ahmedabad High Speed Rail (MAHSR Bullet Train) project.
This is the longest ever girder to be fabricated or manufactured in India. The upcoming Mumbai Trans Harbour Link (MTHL) project’s Package 1 has a 180m Orthotropic Steel Deck (OSD) girder span, but it was manufactured in Japan.
This single-span girder weighs 3000 MT, stands 21 meters tall and is 13 meters wide. Trial assembly for it was successfully completed at Zetwerk’s facility located in Narayanpur, just south of Wardha, in Maharashtra.
Larsen & Toubro – IHI Infrastructure Systems Consortium was awarded MAHSR Bullet Train project Package P4 X & Y’s Rs 1389.70 crore contract by National High Speed Rail Corporation Ltd. (NHRCL) in January 2021. Their scope involves fabricating and transporting 28 steel truss bridges requiring an estimated 70865 MT of steel.
L&T – IHI went on to subcontract 10,000 MT of fabricated girders to Zetwerk in April 2022 with a contract value of Rs. 126.55 crore.
An anti-rust primer is expected to be applied before the girder is dismantled and transported.
The girder’s exact launch location remains unknown to me, but if I had to hazard a guess – it’ll likely be over the Ulhas River in Maharashtra’s Thane District where a 4 span bridge with lengths of 100m + 130m +100m + 130m is planned to be built within 135.45 km Package C3.

September 27 Update: Per Shravan’s comment below, it will be erected right above Delhi – Mumbai Expressway along with another 100m span.
