Mumbai's infrastructure calendar just got a landmark entry. Chief Minister Devendra Fadnavis and Deputy Chief Minister Sunetra Ajit Pawar on Thursday, 13 August 2026 jointly inaugurated, launched, and renamed a clutch of major Mumbai Metropolitan Region Development Authority (MMRDA) projects — signalling a decisive push to untangle the city's notoriously gridlocked arteries.

Four projects, one ceremony: what was inaugurated

The event covered four distinct milestones. The Santa Cruz–Chembur Link Road (SCLR) Phase 2 — stretching from Bharat Nagar Road to Akola Junction — was formally opened to traffic, promising smoother movement into the Bandra-Kurla Complex (BKC), Mumbai's premier financial district. Alongside it, the Chembur Metro Station under Metro Line 2B (Phase 1A) was inaugurated, adding another node to the city's rapidly growing rapid-transit web.

The third and perhaps most dramatic moment: the launch of 'Arjuna', the second Tunnel Boring Machine (TBM) on the Thane–Borivali Twin Tunnel Road Project. With both TBMs now operational, boring on the two parallel tunnels will proceed simultaneously. Finally, the elevated BKC connector linking G-Block, Bandra-Kurla Complex to the Eastern Express Highway was renamed the 'Barrister Babasaheb Anantrao Bhosale Flyover', honouring the late former Chief Minister's contributions to Maharashtra's formation.

Thane to Borivali in 12 minutes: the tunnel that rewrites the map

The Thane–Borivali tunnel is the headline number in today's announcements. Currently, the road distance between the two suburbs is 23 kilometres, and peak-hour travel can consume 90 minutes. The twin-tunnel alignment slashes the effective route to 11 kilometres, with projected travel time of just 12 to 15 minutes. For millions of commuters navigating Mumbai's east-west divide — a geographical challenge the city has grappled with for decades — that is a transformational shift.

CM Fadnavis directed the Brihanmumbai Municipal Corporation (BMC) and MMRDA to move swiftly on clearing the remaining congestion pinch-points along the SCLR corridor, underscoring that today's inaugurations are steps in a longer sequence, not a finish line.

60–70 km of new metro lines expected this year

Speaking at the event, CM Fadnavis projected that 60 to 70 kilometres of metro corridors would become operational within 2026. Once Mumbai's metro network is integrated with the suburban rail system, it will serve the existing 90 lakh (9 million) suburban rail passengers while opening capacity for an additional 70 lakh (7 million) commuters. That combined network would represent one of the largest urban-transit expansions in Asia.

On rolling stock, Fadnavis pointed to a central government decision that will accelerate the manufacture of air-conditioned, automated, modern local trains from 2027 onwards. The new trains are expected to enter Mumbai's suburban network by late 2029 or March 2030 — a timeline that ties the state's metro ambitions to a parallel upgrade of the century-old local rail backbone.

A flyover named for a freedom fighter and state-builder

The renaming of the BKC connector carries historical weight. Barrister Babasaheb Anantrao Bhosale, a former Chief Minister of Maharashtra, was a freedom fighter who championed girls' education, steered the creation of the Aurangabad Bench (now Chhatrapati Sambhajinagar) of the Bombay High Court, and was instrumental in carving out Gadchiroli district. Fadnavis described the naming as a tribute to his foundational role in shaping the state's administrative and social architecture.

Ministers Mangalprabhat Lodha, Girish Mahajan, and Ashish Shelar, along with Minister of State Madhuri Misal, senior legislators, and MMRDA officials were present at the ceremony.

Mumbai has been promised transformative infrastructure before. What is different now is the convergence of tunnels, metro lines, and rail modernisation on overlapping timelines — the city's commuters will be watching every boring metre of Arjuna's progress to see if the promise holds.
