Mumbai's 22-km Versova-Dahisar Link Road project has moved closer to the construction stage, with two giant tunnel boring machines undergoing factory tests in Chennai. The 15.6-metre TBMs will excavate 3 km of the proposed 3.9-km twin underground road tunnels between Malad and Charkop, nearly 40 metres below ground. Scheduled for launch in May 2027, the machines will be transported to Mumbai in parts on around 100 trailers.
