1st Pier of Mumbai Metro Line-6’s Double Decker Ready

J Kumar Infraprojects – CRTG JV’s first pier for a 2.58 km double decker structure on Mumbai Metro’s 15.18 km Line-6 (Pink Line) is now ready on the city’s Jogeshwari–Vikhroli Link Road (JVLR).

This combined pier has been built at Oberoi International School near the upcoming Shyam Nagar Station just east of the Western Express Highway (WEH). It has a width of 1.8m and now consists of two precast prestressed pier caps –

  1. 17.8m wide pier cap for a flyover to support vehicles. 6 T-girders will be launched to build its deck.
  2. 10.56m wide pier cap for a viaduct to support metro trains. 2 U-girders will be launched in the future to build its deck.

The execution of this complex project – connecting Swami Samarth Nagar with Vikhroli – with steep gradients and a total of 53 curves (17 sharper than 300m radius) is being managed by the Delhi Metro Rail Corporation (DMRC). To support its construction without disturbing vehicular traffic, J Kumar Infraprojects in 2020 deployed a massive straddle carrier which is typically seen at shipping ports.

The exact start/end points of the double-decker structure are unknown, but it will come up between Adarsh Nagar Station and Shyam Nagar Station, which is under the ambit of J Kumar – CRTG JV’s Package BC-03.

Its construction contract was awarded by DMRC in August 2018 with a contract value of Rs. 867.75 crore. It involves the construction of a 6.079 km viaduct from chainage – 822.508m to 5257.400m and five stations at Swami Samarth Nagar, Adarsh Nagar, Jogeshwari (W), JVLR and Shyam Nagar.

Below on the left is a design of the double-decker’s combined pier. Metro trains elsewhere on the line will typically run at an average height of 11m above the ground level, but on the double-decker they’ll run at an average height of approximately 19m above the ground.

The diagram on the right shows Line-6’s Adarsh Nagar Station which will consist of 3 levels above the ground level:

  • Level-1: Flyover for vehicles
  • Level-2: Concourse level for ticketing / customer service etc.
  • Level-3: Platform level for metro trains (25m above the ground)

A similar 3 level structure is going to come up at Meditya Nagar on Mumbai Metro’s Line-9 in Mira Bhayandar which is also under construction by J Kumar Infraprojects through Package CA-48. Elsewhere in India, HCC-URCC JV is currently constructing a 4-level structure for Bangalore Metro’s Jayadeva Station. With a pre-existing underpass, that intersection will eventually have a total of 6 levels!

      Mainstream media will cover legal updates as they happen. Bar and Bench & Live Law typically provides more in depth coverage.

      Depot issue won’t affect Line-6’s progress until 2023 imo as station, viaduct and rolling stock tendering/manufacturing are on the ‘critical path’ and more time consuming. If work doesn’t start by then then the depot will become one of the reasons for its overall delay.

    If the turning radius is very steep, what workaround is being used? Special coaches or lower speed (or something else)?

    In case the work around is special coaches, would the line 3 integration (in case the Aarey depot actually moves to Kanjurmarg) be possible?

    Also, is the depot for this line also going to be delayed, given the joint depot idea still hanging around?

    I hope the Maha govt uses some common sense and starts the Aarey work :/

      Details aren’t known, but I imagine trains will be operated at lower speeds. The line’s specs will be made available in the tender docs, so the rolling stock manufacturer will definitely take radius into account while designing the trains. Integration details and the changes required haven’t been published by MMRDA, so can’t really comment.

      Dahanukarwadi (Charkop) to DN Nagar section of Line 2A will open up at a later stage, sometime in 2022 worst case 2023.

        What are they going to start in month of May 2021 for line 2A. The state govt announced opening of line 2A in May 2021 ?

          May is not possible. Train has arrived, but not in a ‘ready’ state. Propulsion tests are underway. if they can start trial runs in May, that’ll be an achievement in itself.

        Is it because work near nullah between Dahanukarwadi and the next station will take more time to complete? That is where the depot is there right?

          The southern section (Depot – DN Nagar) was already lagging behind and pandemic was the last straw. MMRDA asked J Kumar to divert most men/machinery to the northern section to get at least that part opened up.

          Yup, depot-line joins the main-line just south of Dahanukarwadi Station

    Hi

    This project (double decker flyover) is a commendable project … Hats off but I hope they will put outmost attention will implementing it because it will bypass the Western express Highway while going across to connect the Balasaheb Thackeray flyover. This will cause in my opinion huge traffic at the Western express Highway for atleast 60 days if not more.

    Will this also be a 5 level structure at JVLR-WEH junction? (ground level which has intersection, 1st level flyover onWEH, 2nd level flyover on JVLR and 3rd level concourse at JVLR/Jogeshwari East station, and 4th level for trains/platforms)
