JICA has
extended an ODA loan of 211,704 million Japanese Yen (approximately INR 13,658
Crore) for the MTHL Bridge project
·
The first
tranche of loan agreement was signed in March 2017 and the second one in March
2020
· The project is expected to be completed by September 2023
New Delhi,
January 14, 2022: The first
Orthotropic Steel Deck (OSD) span for the 10.380 km of civil work Package 1 section,
western half of the bridge, was erected today.
The civil work Package 1 is awarded to the consortium of Larsen &
Tourbo (L&T) Limited (India) & M/s IHI Infrastructure Systems Co. Ltd.
(Japan).
Financed by Japan International Cooperation
Agency (JICA), MTHL Bridge is an under-construction 21.8 km long six-lane
marine road bridge implemented by the Mumbai Metropolitan Region Development
Authority (MMRDA). Sea crossing section of around 16.5 km and land section of remaining
5.3 km connects Mumbai with Navi Mumbai and is expected to mitigate traffic
congestion in the island city and promote economic development in Navi Mumbai.
The Link has interchanges at Sewri in Central Mumbai, Shivaji Nagar at Mumbai
Bay and NH-4 B at Chirle, Navi Mumbai.
The bridge, when completed, would be the
longest sea bridge in India and would cater to 70,000 vehicles daily.
OSD bridge has lesser self-weight but
stronger structure than concrete or composite girder bridges, which requires
fewer and smaller piers. 180m length OSD, which is applied to the MTHL Bridge,
is world’s
longest level of span length that requires advanced manufacturing technology
and severe quality control. IHI Infrastructure System, under IHI Corporation, a
comprehensive heavy-industry manufacturer, has achieved its highest fabrication
quality by using its group factory mainly in Japan and Vietnam with supervision
of their Japanese higher skilled fabrication engineers. OSD contributes to shorter
construction period and mitigation of safety-risks at the project site since it
is manufactured in a factory and requires lesser on-site work. Moreover, fewer and smaller piers and shorter
construction period mean less impact on environment and ecosystem.
The deck segments were separated into six to eight blocks as 30 MT
maximum and delivered to the site in total 33 shipments by ocean liner. These
blocks were assembled at the project site into erection units, maximum length
180m, maximum weight around 2,600 MT, and moved on SPMT (Self-Propelled Modular
transporter) to the temporary jetty. OSD were loaded onto the special barge
equipped with lifting towers with 16 numbers of 300 MT strand jacks and lifted
up with the strand jacks onto the piers. Then, the barge was towed for 4 to 8km
to the erection location.
Speaking on the
occasion, Mr. SAITO Mitsunori, Chief Representative, JICA India said, “The MTHL Project
is a shining example of JICA’s focus on quality infrastructure and strong
India-Japan partnership. Once completed, the project will reduce the travel
time from South Mumbai to Navi Mumbai from 120 minutes to merely 20 minutes. I
am confident that the project would contribute to decongestion of the island
city and further development of the Navi Mumbai Area. I am very pleased to
inform that Japanese expert had recommended the adoption of the OSD for the
project on account of environmental and navigational challenges and Japanese
companies such as IHI corporation and JFE steel are involved in the project. I
strongly hope that some of the approaches and innovative technologies, adopted
under MTHL become models of excellence, which could be replicated in other
infrastructure projects in India.”
About JICA
Established, by a specific law, as an incorporated administrative
institution under the Government of Japan, the Japan International Cooperation
Agency (JICA) aims to contribute to the promotion of international cooperation,
as a sole Japanese governmental agency in charge of ODA implementation. JICA is
the world's largest bilateral donor agency. JICA works as a bridge between
Japan and emerging countries, and provides assistance in forms of loan, grant and
technical cooperation so that the emerging countries can strengthen their
capabilities.

About MTHL:
The Mumbai Trans Harbour Link, also known as the
SewriNhavaShevaHarbourLink is a under-construction of about 22 km long, 6-lane
bridge with about 16.5km long over the sea and about 5.5kms long viaduct on
land on either side. The Link has interchanges at Sewri in Central Mumbai,
Shivaji Nagar at Mumbai Bay and NH-4 B at Chirle, Navi Mumbai. The MTHL will
feature approach sections, interchanges, intelligence transport system (ITS)
and the other amenities required for a sea bridge. The traffic conditions on
the stretch will be monitored and managed from the traffic control centre with
the help of CCTV cameras and related facilities installed on the stretch. The
total of length of spans of the OSD superstructure in both carriageways of MTHL
is about 6.41 km. The width of the steel superstructure is about 14.92m for
each carriageway.
The total steel quantity to be used for the OSD superstructure in
MTHL will be about 87,452 MT. The span erected on 14th January 2022 has length
of 118.8 mtrs with total weight of about 1331 Mt. This is a very important
stage and it accelerate the construction of MTHL that will connect South Mumbai
to the Navi Mumbai in a mere 20 minutes as compared to the current travel time of
120 minutes.
About
Orthotropic Steel Deck (OSD) Construction at MTHL:
The
Orthotropic Steel Deck is a steel Deck Superstructure (strengthened or
stiffened both transversely and longitudinally which will carry the vehicular
load more efficiently among three planes and improve the load-carrying capacity
of the bridge as compared to Concrete Superstructure for similar span. OSD
Steel Deck Superstructure has lesser self-weight than concrete or composite
girders and a longer span of 180 mtrs is designed using OSD for this project by
the Contractor (L&T-IHI Consortium). OSD is the ideal solution considering
MTHL site conditions (Navigational Channels, Discharge Channels) and longer
Pier to Pier distances. It is also more cost-effective compared to the Cable Stay
or Suspension bridges.
The steel
spans are fabricated in fabrication workshop facilities located in
Japan,Vietnam, Taiwan etc. and delivered to India which will enable faster
construction work and lessen deck-related on-site activities. The final assembly,
of 1st OSD span was done in last fortnight of December 2021 and load-out
/erection of the superstructure at Pier Location MP124N-125N was carried out
on-site on 14th January 2022. A barge, which was specifically designed and
manufactured by L&T at its own Shipbuilding facility at Kattupalli, Chennai
is being used for the transportation of these heavy Orthotropic Steel Deck
(OSD) sections. This is a flat top ballastable barge having weight of 5359 MT
with 110 mtrs in length and 64 mtrs in breadth which is equivalent to size of
actual football ground area. The depth of the barge is 6 mtrs with deck
strength of 15 T/m2.
