Maharashtra Chief Minister Devendra Fadnavis on Wednesday launched the Tunnel Boring Machine (TBM) for the state’s ambitious 9.23-km underground road corridor that will connect Orange Gate on the Eastern Freeway to Marine Drive. The launch marks a major milestone in one of Mumbai’s most significant infrastructure projects aimed at strengthening east–west connectivity.
Fadnavis was joined at the ceremony by Deputy Chief Minister Eknath Shinde, Maharashtra Assembly Speaker Rahul Narwekar, and several senior officials and dignitaries. With the activation of the TBM, full-fledged tunnelling work on the corridor has officially commenced.
