The bridge was officially inaugurated on April 14, 1987, by the then-Prime Minister of India, Rajiv Gandhi.
The project was executed by the Brahmaputra Board and involved complex river-training works to stabilize the bridge piers.
The name commemorates Koliabhomora Phukan, an 18th-century Ahom military commander who served under King Gaurinath Singha.
The design includes 23 main spans and two end spans, utilizing a balanced cantilever construction method.
It was specifically engineered to withstand the extreme discharge and unpredictable seasonal flooding of the Brahmaputra River.
The construction of the bridge significantly reduced travel time between northern and southern Assam by bypassing the traditional ferry system.
The bridge's foundation is built deep into the riverbed to anchor against shifting sands and high-velocity water flow.
The Koliabhomora Bridge is a 3.015-kilometer prestressed concrete bridge spanning the Brahmaputra River in Assam, India. It serves as a vital strategic connection between Tezpur on the north bank and the Nagaon district on the south bank. Completed in 1987, the bridge was named after Ahom General Koliabhomora Phukan. It functions as a crucial link for National Highway 715, facilitating transit between Upper Assam and the rest of the country. The structure consists of 23 spans, each measuring 120 meters in length. It is widely recognized for its engineering significance in navigating the challenging, silt-heavy currents of the Brahmaputra. The bridge features pedestrian walkways on both sides, allowing for river views. It remains one of the primary transit points for heavy freight and passenger vehicles in the region.
The riverbanks near the northern approach in Tezpur offer the best vantage point for capturing the full length of the bridge.
Pull over at designated safe zones near the bridge approaches if you wish to view the river, as stopping on the main span is strictly prohibited.
Exercise caution during monsoon season due to high winds and heavy river spray.
Visit during the late afternoon to experience the scale of the river during the transition to dusk.
Attempting to walk across the entire span of the bridge, as it is a major high-speed highway thoroughfare.
Do not litter into the river; follow local traffic safety protocols regarding vehicle stopping.
