Nepal Multi-span Bridge

The Dodhara Chandani Bridge is Nepal's longest multi-span pedestrian suspension bridge, spanning 1,452.96 meters across the Mahakali River.Dodhara Chandani BridgeThe Dodhara Chandani Bridge, also known as the Mahakali Bridge, is located in the Kanchanpur District of Far-Western Province, Nepal, connecting the villages of Dodhara and Chandani . Constructed between 2004 and 2005, it serves as a vital link for communities near the Indo-Nepal border, facilitating pedestrian, bicycle, and motorcycle traffic . The bridge is a sequence of four suspension bridges supported by eight steel pylons, anchored to large blocks on both riverbanks and three common anchor blocks in the riverbed . Each pylon reaches 32.72 meters in height, with main spans of 225.40 meters and smaller spans of approximately 70 meters, forming a series of arches . The bridge deck is 1.60 meters wide, made of sturdy metal grating, with handrails and wire mesh for safety .Other Multi-Span Bridges in NepalNepal has a rich network of long-span suspension and trail bridges, particularly in remote Himalayan regions . These bridges typically span 100 to 200 meters per main span, using high-tensile steel cables and wire mesh or wooden planks for the deck, primarily supporting pedestrian and light cargo traffic . Notable examples include:Baglung Parbat Footbridge: A 567-meter suspension bridge over the Kali Gandaki River, recognized as the world's longest pedestrian suspension bridge .Koshi Barrage: A 1,149-meter bridge with 56 spans in Sunsari District, serving as a major vehicular crossing .Karnali River Bridge: A 1,015-meter bridge with 20 spans using RCC T-beam and prestressed box girder construction .Trail Bridge ProgramsNepal has implemented the Trail Bridge Sector Wide Approach Programme (TB SWAp) to enhance connectivity across all seven provinces . The program supports the construction of short-span (120 m) bridges, with provincial governments and federal agencies coordinating technically complex or strategic bridges . Over 9,500 trail bridges exist in Nepal, serving more than 17 million people, with ongoing initiatives to construct, maintain, and upgrade bridges to improve accessibility, safety, and resilience against floods and earthquakes .SignificanceMulti-span bridges like the Dodhara Chandani Bridge are crucial for connecting isolated communities, enabling access to markets, schools, and healthcare, and supporting local economies . They also serve as tourist attractions, showcasing Nepalese engineering and the scenic beauty of river valleys. The combination of engineering innovation and social impact makes these bridges a vital part of Nepal's infrastructure network.
