Segment Launching For Bangalore Metro’s Reach 4B to Begin Soon

With a series of new piers cast on Kanakapura Road, NCC Limited, the contractor for Bangalore Metro’s 6.29 km Reach 4B project to Anjanapura in Phase 2 has started bringing in equipment for setting up a Launching Gantry to launch precast segments and construct the southern extension of the 24.20 km Green Line’s viaduct.

Launching activity is expected to commence within the next 2 months near the under construction Mantri Serenity & Arena Mall development (view on google maps) in Vasanthapura where the Krishna Leela Park station is marked below, and progress southward towards the Vajrahalli station where the Launching Gantry will be dismantled and set up again for building the viaduct towards Thalaghattapura.

More parts of the LG are going to arrive in the coming weeks and then be amalgamated & hoisted using a crane. See an example of how it’ll eventually look like here.

On a side note, with multiple developers approaching the BMRCL for dedicated station access, there’s a possibility of Mantri’s Arena Mall being connected to the Krishna Leela Park Station in the future and even lending its name to the station. The developer’s promotional video and layout both include dedicated connections, but there hasn’t been an official confirmation on it from either the developer or the BMRCL.

Coming back to construction, I’ve shared this previously in other cities’ posts, but it’s a good time to rewatch this 1 minute video demonstrating how the Launching Gantry works its magic with precast segments to build modern segmental viaducts and bridges:

The segments shown in the video above are currently being churned out and stacked by NCC at their casting yard in Thataguni Village. The ones seen seen in my tweet below will be the very first ones to get launched.

    What about Whitefield extension? When will work start?

  2. Ganesh says:

    Thank you TMRG for the demo video. I personally saw this type of construction for BETL highway on NH7 and Bandra-Worli Sealink in Mumbai.

  3. Santhosh says:

    Work started in Mysore road before this stretch and they are ahead. What about Mysore road ? Are they in delay ?

    • TMRG says:

      Yes, they were (are still?) waiting for approvals to cut down trees. This stretch is doing a little better than the Mysore Road one.

    I moved into an apartment right next to vajarahalli station in metro Reach 4B and must say that NCC is working at a frentic pace.had some issue in travelling initially but looks ok now.Just wondering how it will in Whitefield road. Man that stretch is a nightmare

    @tmrg .. monthly news letter plz

    Heartened to see the progress on this stretch. Great work NCC, keep it up. But considering current population density of this area which is quite low (two full barren layouts – anjanapura and bsk 6th stage), more urgency shd have been shown for other reaches of phase 2, especially the line to ecity via silk board and the one to whitefield. Those two lines are need of the hour, ppl r dying daily commuting on those stretches.

    • Pradeep says:

      But even this stretch has enough traffic and all big constructions are happening here currently. By the time they finish in another 2 yrs, it will be very busy. Glad that they are doing it very fast. Yes Electronic City & Whitefield stretch needs importance. We in the south can consider ourselves lucky.

    What i am seeing from the construction updates is that, there is a huge lobby which is driving the metro construction. For e.g.
    1. Whitefield Line – If this construction is started and completed then real estate prices shall come down in whitefield area as traveling time shall reduce. Who are the losers here,
    a. Real Estate Agencies
    b. Cabies
    c. BMTC

    I see a huge lobby behind this, better i stay away from posting this as there is dangers in pointing out….. I am not sure if funding agencies are keeping track of construction progress.
