Mumbai Trans Harbour Link: Two Firms In Fray To Operate And Maintain India's Largest Sea Bridge

GR Infraprojects (GRIL) and Gawar Constructions are the sole contenders that have tendered bids for the operations and maintenance (O&M) contract of the soon-to-be-inaugurated Mumbai Trans-Harbour Sealink (MTHL).

Earlier in October 2023, the Mumbai Metropolitan Region Development Authority (MMRDA) had invited global tenders from experienced firms for operation and maintenance of the mega infra project.

Once the bid is finalised, the company which bags the bid will maintain the project facility for the contract period of 24 months (two years), reports the MetroRailGuy.

The scope of the contract also includes maintenance of civil structure and operation of Advanced Traffic Management System (ATMS) works.

Named as Atal Bihari Vajpayee Sewri – Nhava Sheva Atal Setu after the former Prime Minister of India Late Atal Bihari Vajpayee, the project connects Sewri on the Mumbai side with Chirle on the Navi Mumbai side in Maharashtra.

The project comprises construction of approximately 21.8 km long and 6-lane wide carriageway viaduct across the Mumbai Bay. It consists about 0.5 km of land viaduct at Sewri, about 16.3km of viaducts over sea/creek and about 4.9 km of viaduct and earth sections on land on Navi Mumbai side.

This Sea link project commences from Messant Road at Sewri where it connects with the Eastern Freeway and ends at mainland at Shivaji Nagar in Navi Mumbai, providing commuters with a seamless and swift 20-minute journey between these two key locations, free from traffic signals.

This fully access-controlled highway will have four interchanges, toll collection facilities and other necessary facilities and buildings to safely and efficiently operate the project after completion. The project also conforms generally with the relevant expressway standards and has a design speed of 100 km per hour.

The country’s longest sea bridge is expected to be inaugurated by Prime Minister Narendra Modi on 12 January.
