96% work on trans-harbour link complete ahead of December deadline, ET Infra

MUMBAI: Mumbai Metropolitan Region Development Authority (MMRDA) has achieved more than 96% progress on the Mumbai Trans Harbour Link Road (MTHL) as work is in full swing to complete it by this December.

All works related to building the viaduct and barriers are done and now the focus is on asphalting, installation of light poles, CCTV cameras and toll infrastructure.

An MMRDA official said, “All the ramps at Sewri Interchanges (Sewri, Shivajinagar and Chirle) connecting local roads on either side are complete. Bituminous works on these roads are in progress.”

The bidding process for appointment of a contractor for a connector between Chirle and the Expressway is in process.

A total of 1,212 lighting poles are to be installed as part of the project, of which 629 poles are already in place.

These poles are equipped with a central control and monitoring system (CCMS) and have been specifically designed to withstand the challenges of being situated in the deep sea. These poles are suitable for saline environments and have corrosion-free polyurethane coating and galvanization to prevent rusting to prolong the lifespan, a structural design to withstand high wind velocities and uniform illumination throughout the bridge.

Additionally, the poles will be equipped with a lightning protection system to safeguard against potential damage caused by lightning.

Moreover, 78 of the total 130 CCTV poles have been erected. Construction of the operation and control centre is also at an advanced stage.

MMRDA said it has completed 50% work on the toll infrastructure.

MTHL is a 22km-long sea bridge with a 16.5km sea portion and 5.5km of land, thus connecting the island city to the mainland.

When completed, the sea bridge would be the longest in India and cater to 70,000 vehicles daily.

Around 14,000 people were employed when work was at its peak for this project that required skilled workers at all stages of construction.

Building of the Sewri side of the bridge as well as the land work went to a consortium of Larsen & Toubro (L&T) and Japan’s IHI Infrastructure Systems. The Navi Mumbai side of the bridge was assigned to Daewoo-Tata. Work on the ground began in April 2018.

Meanwhile, the project cost escalated from Rs 4,500 crore in 2005 to Rs 17,843 crore in 2018, about 85% of which was funded by a loan from the Japan International Cooperation Agency (JICA).
