The Mumbai Trans Harbour Link, India's longest bridge, is expected to open to the public by the end of this year. This week, Maharashtra Chief Minister Eknath Shinde and Deputy Chief Minister Devendra Fadanvis will flag off a 'bus' to travel a short distance on the Mumbai Trans Harbour link, marking a key milestone. To commemorate the completion of the deck slab installation, Shinde and Fadanvis will wave the green flag to a bus carrying MMRDA officials and engineers, which will take a symbolic short drive on the new route, according to an official.

Following the symbolic ceremony, the remaining stages will be completed over the next four to five months, including the installation of crash barriers, asphalting the deck, erecting view-cutters, establishing the open toll collection centers, security and surveillance system, markers and signages, waterproofing the engineering structure, lights and reflectors, and so on.
