SPS Construction India has completed construction of the new Guwahati–North Guwahati Bridge over the Brahmaputra River, with the project set to be officially inaugurated on February 14, 2026, by Prime Minister Narendra Modi.
Spanning approximately 1.24 kilometres, the six-lane bridge has been built using an extradosed pre-stressed concrete design, a hybrid structural system that combines features of box girder and cable-supported bridges. The design enables enhanced span efficiency while maintaining deck stiffness and long-term load stability, making it particularly suitable for high-traffic urban corridors.
Engineering Over Complex River Terrain
Constructed across one of India’s most challenging river systems, the project required detailed geotechnical investigations and hydraulic modelling prior to foundation work. The Brahmaputra’s shifting sediment profile, fluctuating water levels, and high monsoon discharge presented significant execution challenges.
SPS Construction India deployed specialised deep-drilling systems and implemented staged cofferdam arrangements to stabilise substructure activity while minimising disruption to the river’s active flow. Detailed river morphology studies were undertaken before pier construction to mitigate structural and hydraulic risks.
Superstructure erection involved calibrated cable tensioning and deck alignment sequences, supported by continuous structural monitoring to maintain equilibrium across spans. Pre-stressed concrete elements were installed under controlled stress conditions, with alignment checks conducted at every stage to ensure geometric precision.
Temporary marine logistics platforms were also deployed to facilitate the movement of heavy components and maintain alignment accuracy during erection. Continuous weather tracking and river-level monitoring were incorporated, particularly during peak monsoon periods.
Boost to Regional Connectivity
The bridge forms a critical link between Guwahati and North Guwahati and is expected to significantly reduce travel time, ease congestion on existing crossings, and improve movement of commuters, freight and long-distance travellers. By limiting the number of piers within the active river channel, the design balances structural stability with hydraulic sensitivity.
The project supports Assam’s broader infrastructure roadmap and aligns with national efforts to enhance connectivity in the Northeast region. Improved access between the northern and southern parts of Guwahati is expected to strengthen logistics efficiency, support local businesses, and facilitate long-term urban expansion.
Company Statement
Rohit Singla, Director, SPS Construction India, said the project reflects coordinated planning and sustained institutional support.
“This bridge is the outcome of a clear infrastructure vision and sustained support from the Government, aimed at strengthening connectivity in Assam and the Northeast. Our role as the executing agency was to translate that vision into a durable, safe and functional structure,” he said.
“Constructing an extradosed bridge over a river such as the Brahmaputra required managing hydrological unpredictability, deep foundation complexity and high-precision cable calibration simultaneously. We are proud to have delivered a structure that will serve the region’s mobility needs for decades.”
A Milestone for Advanced Bridge Engineering
The project reflects a broader shift toward technically advanced bridge typologies in urban river environments, where structural performance, lifecycle durability and environmental management must be addressed concurrently.
With the bridge now completed and ready for formal dedication, it marks a significant milestone in Assam’s transportation infrastructure and a key addition to India’s evolving portfolio of high-performance river-crossing structures.
