Mumbai: First Steel Bridge for Bullet Train Project in Maharashtra Launched Over Nashik Highway
Mumbai, 28th September 2026: The first steel bridge completed for the Mumbai–Ahmedabad Bullet Train Project in Maharashtra has been launched over NH-3 (Nashik Highway) at Dive-Anjur village in Bhiwandi, Thane district. The 100-metre-long bridge weighs 1,405 metric tonnes and has been installed to facilitate the high-speed rail corridor.
The bridge was fabricated at a workshop in Trichy, Tamil Nadu, nearly 1,300 km from the launching site. After fabrication, the steel components were transported to Maharashtra on trailers, assembled at the site and subsequently installed over the highway.
The bridge measures 100 metres in length, 14 metres in height and 14 metres in width. Its installation was carried out during night-time traffic blocks on the National Highway to minimise disruption to highway traffic.
At the site, the bridge was assembled on temporary trestles positioned about 17.5 metres above ground level. The assembly involved 22 skid arrangements and 54,076 Tor-Shear Type High Strength Bolts (TTHSB). A C5 protective painting system and elastomeric bearings have also been provided.
The completed structure was pulled into its final position using an automatic mechanism comprising two hollow jacks, each with a capacity of 150 metric tonnes, along with pre-tensioned Macalloy Bars.
The fabrication process included precision cutting, drilling, welding and painting as per the prescribed designs, drawings and specifications. Each batch of steel underwent Ultrasonic Testing (UT), while welders and supervisors involved in the work were certified by International Welding Experts.
Steel bridges are being used at locations on the Mumbai–Ahmedabad Bullet Train corridor where longer spans are required, including crossings over highways, expressways, major rivers and railway lines.
Of the 28 steel bridges planned for the Mumbai–Ahmedabad Bullet Train corridor, 16 have been completed.
