Core Event: Installation of Maharashtra’s First Steel Bridge
A 100-metre-long steel bridge weighing 1,405 metric tonnes was launched over National Highway-3 (the Nashik Highway) at Dive-Anjur village in Bhiwandi, Thane district. The structure, 14 metres high and 14 metres wide, was assembled on temporary trestles about 17.5 metres above ground using 22 skid arrangements and 54,076 Tor-Shear Type High-Strength Bolts. An automated system with two 150-tonne hollow jacks and pre-tensioned Macalloy bars pulled the bridge into its final position during night-time traffic blocks to minimise disruption to motorists.
Background & Context
The Mumbai-Ahmedabad High-Speed Rail (MAHSR) corridor, India’s first bullet-train line, was inaugurated on September 14 2017 when Prime Minister Narendra Modi and former Japanese Prime Minister Shinzo Abe laid the foundation stone in Ahmedabad. Roughly 81 % of the project’s estimated INR1.08 crore cost is financed through Official Development Assistance from the Japan International Cooperation Agency (JICA), with the remainder funded by the Government of India. The line is designed for speeds of up to 320 km/h, reducing travel time between the two state capitals to about two hours seven minutes and featuring ten scheduled stops.
Data & Statistics
- Bridge length: 100 metres
- Bridge weight: 1,405 metric tonnes
- Height/width: 14 metres each
- Assembly height: ? 17.5 metres above ground
- Fastening: 54,076 high-strength bolts, 22 skid arrangements
- Launch mechanism: two 150-tonne hollow jacks, pre-tensioned Macalloy bars
- Total steel bridges planned for the corridor: 28
- Completed steel bridges after this launch: 16 (including this structure)
All figures are reported by the National High-Speed Rail Corporation Limited (National High Speed Rail Corporation Limited (NHSRCL)) and corroborated by multiple Indian news outlets.
Official Statements & Responses
The agency also noted that the bridge’s C5 protective painting system and elastomeric bearings are intended to enhance durability and vibration control—critical requirements for high-speed rail infrastructure.
The official reaffirmed Japan’s commitment, alongside India, to bring high-speed trains into operation in the coming years.
Criticism & Opposition
The Japanese official’s scheduled remarks constitute formal criticism of the current pace of work, indicating that the anticipated schedule set at the project’s inception has not been met. This assessment contrasts with Indian officials’ portrayal of “steady progress” on the ground.
Why It Matters / Impact
The bridge’s successful launch demonstrates the logistical scale of the MAHSR project: components fabricated in Trichy, Tamil Nadu, travelled roughly 1,300 km by road before on-site assembly and installation. The achievement underscores India’s “Make in India” objectives by illustrating domestic capacity to produce and deploy large, precision-engineered infrastructure for a technologically advanced rail system. Moreover, the use of steel bridges at long-span crossings—over highways, expressways, rivers and existing rail lines—facilitates uninterrupted high-speed alignment, a prerequisite for achieving the line’s design speed and travel-time targets.
What’s Next
India and Japan are slated to hold a “two-plus-two” dialogue by the end of the year, providing a platform to review project milestones and address the timeline concerns raised by Japan. Additional steel bridges will continue to be fabricated, transported, and installed as the corridor advances toward its target of completing all 28 bridges. The broader high-speed rail project aims to commence passenger services within the next few years, contingent on the timely completion of remaining civil works and rolling-stock procurement.
