The Mumbai–Ahmedabad Bullet Train project has installed Maharashtra’s first steel bridge over National Highway 3 near Dive-Anjur village in Bhiwandi taluka, Thane district, marking a major construction milestone for the high-speed rail corridor.
The bridge is 100 metres long and weighs 1,405 metric tonnes. It was installed using complex engineering techniques at a site along the Nashik Highway, where the railway alignment crosses the national highway. The structure was manufactured at a workshop in Tiruchirappalli, Tamil Nadu, around 1,300 kilometres from Maharashtra, before being transported to the Thane site by trailer.
According to the report, the bridge was assembled near Dive-Anjur after the fabricated steel structure was brought from Tamil Nadu. Its construction involved steel cutting, drilling, welding and painting in accordance with prescribed technical standards. The installation demonstrates the logistics required to move and assemble large railway structures across state boundaries while work continues on the bullet train corridor.
Each batch of steel used in the bridge underwent ultrasonic testing, or UT, to check the material for internal defects. Welders and supervisors involved in the work were certified by international welding experts, according to the report. These quality-control and workforce-certification measures form part of the technical process for constructing the project’s large steel structures.
The bridge is being viewed as an example of India’s domestic manufacturing capability for complex steel components used in major rail infrastructure. Its manufacture in Tamil Nadu and subsequent assembly in Maharashtra also highlights the distributed nature of the project’s construction supply chain, with specialised fabrication and on-site installation being carried out in different locations.
The Mumbai–Ahmedabad Bullet Train project requires elevated and specialised structures at locations where the railway alignment intersects existing roads and other infrastructure. At Dive-Anjur, the steel bridge has been installed above National Highway 3, allowing the high-speed rail works to proceed across an important road corridor.
The installation is part of the continuing construction activity for the Mumbai–Ahmedabad corridor, which runs through Maharashtra and Gujarat. The reported milestone adds to the project’s sequence of civil and structural works, but the supplied report does not provide a completion date for the wider corridor or an operational timeline linked specifically to this bridge.
Further construction activity and project milestones will determine how the installed structure is integrated with the adjoining sections of the bullet train alignment.
