The Mumbai Trans Harbour Link (MTHL) is a 22km sea bridge connecting Mumbai with Navi Mumbai, making it India’s longest sea bridge. This six-lane highway includes a 16.5km sea bridge section and 5.5km of approach roads on both ends. The project faced numerous challenges, including deep-sea foundations, seismic considerations and the need to minimise environmental impact on the nearby flamingo sanctuary.

The MTHL is expected to reduce travel time between Mumbai and Navi Mumbai from 2 hours to 20 minutes. This improved connectivity was projected to unlock $4.2 billion in industrial investments in the Navi Mumbai region and significantly decongest Mumbai’s existing eastern and western express highways.

Our team provided crucial support to a marine construction subcontractor involved in the bridge’s segmental construction. We offered expertise in international best practices for marine construction and assisted in optimising their workflow to meet the project’s stringent timelines. We helped improve their productivity by 25% and fully comply with international marine construction standards.
