Mumbai – Ahmedabad Bullet Train’s Longest Girder Assembled
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.
If someone is aware, then do leave a comment below or shoot me a message via the Contact page. I’d like to add it in here for everyone’s awareness.
September 27 Update: Per Shravan’s comment below, it will be erected right above Delhi – Mumbai Expressway along with another 100m span.

This Girder seems to be over NH 48 or DM EW it seems, where the piers are already done.
Why so much rust on a newly built structure? Not an expert but is it okay to have such rust on these newly built structures?
Its under trialed at Work shop after completion of fabrication work with followed by Drawings. After successfully checking as per competent authority it will be dismantled and send to Painted shop ,Where firstly it will free from rust followed by Grid/Sand Blasting than will painted as Per IS code with 3 or 4 Coats and will dispatched to required locations.
Are bhai usse kuchh nhi hoga usko new kar denge firse
We EHES LIMITED have assembled n manufactured largest size in terms of width and height of 24mtr wide x 26mtr height x 120 mtr long and it was being dispatched in 6 part assembly condition to Canada using Hazira Port facility.
Before assembly must do galvanized.so that rust cannot observe .
Before assembly do deep galvanized
It is done after assembly so that any changes that might be needed can easily be done.
The people who are doing the work know more than you. So it is better not to comment on the issues you don’t have knowledge about.
Most probably chainage may be 327 or 333 . chance of crossing DFCC or expressway.
It is combination of 100 plus 130.
333.606 most likely chainage.
Anyone know why Surat is building 2 Metro lines and a bullet train station with no connection between them? One Metro line follows the same road as the bullet train station, but ends just a few km away. It seems so basic. What am I missing?
Bad planning and nothing else.
Surat metro dpr was approved before bullet train so that is why no connection.
If our planners were smart enough, they would have already planned an extension and probably classed it phase 1A or something but no they won’t do that because reasons
This right here! Pains me to see absolutely no talk / discourse about this missing interconnection.
@ The Metro Rail Guy,
I would like to correct the mentioned launching location. The above shown girder will be launched where alignment of MAHSR is crossing Vadodara Mumbai Expressway @NHAI Chainage376+076 and NHSRCL Chainage 416+165. where a 2 Continuous span bridge with lengths of 130m + 100m to be erected under P1-C Package of MAHSR project.\
I’m delighted to be directly involved in the Erection of such a giant bridges.
