The longest sea crossing bridge in India is under way in Mumbai
COWI has been awarded the contract for the detailed design of the Mumbai Trans Harbour Link bridge in India.
India is increasing its focus on new infrastructure to support the country’s significant economic growth rates. The Mumbai Trans Harbour Link, a new 22.8 km sea crossing bridge, is an important part of this development.
The bridge will provide a crucial upgrade of the infrastructure connecting south Mumbai with Navi Mumbai and is expected to cut travel time by an hour.
Furthermore, the link will connect to to Nhava Sheva Port, Mumbai-Goa Highway, Mumbai-Pune Expressway and the upcoming Navi Mumbai International Airport. The link is an economic gateway and expected to boost the economic activity in the entire region.
The bridge will traverse through Sewri mudflats, Pir Pau Jetty and also Thane Creek channels. In a first for India, this project will also include an orthotropic steel deck crossing several obligatory navigation channels.
The harbour link has been underway since the seventies and several suggestions for bridges have been made. The contracts are now signed and the works are expected to start this month with an estimated construction time around 4.5 years.
During 2016 and 2017 COWI provided the tender design for a contractor joint venture consisting of Larsen & Toubro Ltd (L&T) from India and IHI from Japan. The L&T-IHI JV was late 2017 awarded the Design-Build contract for package 1 of the project which with a length of more than 10km is the longest of the 3 packages. COWI has subsequently signed the contract for detailed design of package 1.
The design work will be a global COWI collaboration mobilising a strong team from Gurgaon in India, Copenhagen and London.
Project Director Lars Thornfeldt Sørensen has been heading the tender process.
”We had an excellent collaboration with the L&T-IHI JV during the tender stages and I am confident that this will continue in the detailed design phase. We have a great team and will deliver this fantastic bridge project.”
Double in size
The award of the contact cements COWI's position as the global leader in the design of long sea crossing bridges and will be a strong contributor to fulfil COWIs ambitions to double the size of the international infrastructure business.
"We have worked with design of bridges in India for a number of years and the Mumbai Trans Harbour Link has been on the agenda for some time as one of the largest bridge projects in India. We are therefore very proud to be part of the team that are going to make it happen,” says COWI Senior Vice President for Bridges Henrik Andersen.
