Mumbai's Bellasis flyover soon to be opened for public, BMC completes reconstruction of 130-year-old bridge

Railway NOC for Bellasis flyover was likely on Wednesday.

"A joint inspection conducted with BMC officials on January 20 at the Bellasis ROB,  Mumbai Central. The reconstruction of ROB has been completed in all respect and ready for the opening of vehicular traffic. The railway portion has been rebuilt by Western Railway while approaches on east and west by BMC. The NOC for opening road traffic over ROB will be issued on Wednesday," an official told mid-day.

According to the Mumbai civic body, the project still had nearly four months remaining as per the tender conditions. The work order for the flyover was issued in September 2024, and construction began on October 1, 2024.

The BMC said the project was completed ahead of time due to excellent coordination between the Municipal Bridges Department, the Railway authorities, the concerned ward office and the Traffic Police. Round-the-clock work, detailed planning and disciplined execution played a key role in the early completion of the flyover.

While railway-related works were carried out by the Railways, the BMC completed girder bracing, deck sheet installation, slab casting and construction of the approach roads.

Old British-era bridge rebuilt

The Bellasis flyover, originally built during the British era around 130 years ago, had been declared unsafe. Following this, the BMC undertook its demolition and complete reconstruction as part of its infrastructure upgrade programme aimed at reducing travel time and improving road quality for Mumbaikars.

Under the guidance of BMC Commissioner and Administrator Bhushan Gagrani, the civic body has taken up several major infrastructure projects, including flyovers, railway overbridges and cement concrete roads across the city.

Project faced several challenges

Officials said the project was challenging due to multiple constraints, including the relocation of BEST buses, removal of 13 obstructing structures with rehabilitation of affected residents, demolition of a boundary wall of a nearby housing society, and legal proceedings before the Bombay High Court.

Despite these hurdles, engineers ensured that the project remained on schedule. Construction continued even during the four-month monsoon period due to careful planning and phased execution.

Key flyover Details

The Bellasis flyover has a total length of 333 metres, with 138.39 metres on the eastern side, 157.39 metres on the western side and 36.90 metres within the railway limits.

The carriageway is 7 metres wide and includes adequately wide footpaths on both sides.

Traffic relief for south Mumbai

Located on Jangir Boman Behram Marg (earlier known as Bellasis Road), the flyover serves as a crucial east–west link over the railway tracks, connecting Mumbai Central, Nagpada and Tardeo.

Once opened to traffic, the flyover is expected to restore east–west connectivity that had been disrupted for nearly two years and significantly ease congestion on Jangir Boman Behram Marg, Dadasaheb Bhadkamkar Marg (Grant Road), Pathe Bapurao Marg and the Mahalaxmi station bridge.

Final clearances awaited

Additional Municipal Commissioner (Projects) Abhijit Bangar said the successful early completion of the Bellasis flyover demonstrates that infrastructure projects can be delivered ahead of schedule through strict planning and efficient implementation, even in the face of challenges.

He added that the finishing work on the flyover was completed on 6 January 2026, and that load testing, structural stability certification and safety certification have already been obtained.

The flyover will be opened to traffic after receiving a no-objection certificate (NOC) from the Railway authorities, in coordination with the traffic police.
