1st Span Completed for Ahmedabad Metro’s Sabarmati Bridge
The first 41 meter long span of Ahmedabad Metro Phase 1 project’s 298.20m Sabarmati Bridge, which lies partially over the river’s water channel, is now complete.
This crucial bridge on Ahmedabad Metro’s 20.737 km Line-1 comprises of 8 piers with 7 spans ranging between 38.2m to 43.8m. Segment launching works commenced earlier this month following the completion of all piers within the river, which was quite challenging as a group of piles had gotten flooded last year.
Construction here is being carried out by Tata Projects Ltd – China Civil Engineering Construction Corporation (TPL-CCECC) JV as part of the 39.259 km Phase 1 project‘s Reach-2 which was awarded in January 2017 with a value of Rs. 721 crore.
This bridge linking Old High Court Station and West Ramp will have an incline ever so slightly and be 14.209 meter tall at its highest point (Pier P244) and 11.693m at its lowest point (Pier P249). Within the river, it will be 263.60m long and comprise of 6 piers from Pier P244 (towards Thaltej Gam) to P249 (towards Vastral Gam).
More design design details can be viewed in this post from January 2021.
Here are some snaps via a follower. The first span comprises of 13 x 2.8m wide segments and 2 x 2.25m segments:
The team is targeting to complete launching works in the next 2 months.
This bridge is on the extreme eastern-end of Ahmedabad Metro’s Reach-2. On the extreme-west, TPL-CCECC is constructing a 165 meter long balanced cantilever (CLC) bridge at Thaltej – see some snaps from December 2020 and February 2021.

Is it yet confirmed that which is the final logo of Mumbai Metro? People often confuse with MOOPL’s logo, MMMOCL’s logo, MMRDA’s logo, MMRC’s logo and the old blue Mumbai metro logo designed like a high speed train.
There is no final logo as Mumbai has no central authority.
Line-1 has MMOPL’s logo
Line-3 will sport MMRC’s logo
Rest will see MMRDA (owner) and MMMOCL’s (O&M) logos
2 months for 7 spans, that’s roughly one span a week..is that a usual speed of the launcher? or can it go faster (without compromising on safety)??
In normal one launcher can do 1.5-2.5 spans per week
but this is on river
actually launching speed can be same but
transportation speed will be less
as it is on river so we cant compromise safety either
This particular span was lifting with suspender bar scheme because lifting hoiest position was comming at inside of river and LG is having fixed lifting hoiest so suspender can lift max. Two segments in a day only and lifting of segment and transportation of segment can transport only in night soft so one complete span can launch in 15 to 17 days.
Front support have to dismantle and erection on next pier for every span before auto launching, its time taking activity.
casting yard also so far from this segment lifting point (Approximately 20km)
yeah
