Sigandur bridge: Sagara Welcomes India’s Second Longest Cable-Stayed Bridge

India’s second longest cable-stayed bridge, a true engineering marvel, was inaugurated today in Sagara, Karnataka. Spanning the scenic Sharavathi backwaters, this bridge is set to transform regional connectivity, boost tourism, and improve the daily lives of thousands. The India’s second longest cable-stayed bridge is not just a feat of modern engineering but also a long-awaited solution for communities isolated by water for decades

Key Features of the Bridge

• Length: 2.44 kilometers, making it the longest in Karnataka and the second longest in India.
• Location: Across the Sharavathi backwaters, connecting Ambargodlu and Kalasavalli on National Highway 369E.
• Cost: ₹472 crore, sanctioned by the Ministry of Road Transport and Highways (MoRTH).
• Structure:
  • 16-meter-wide deck with an 11-meter carriageway and 1.5-meter footpaths on both sides1.
  • 604 box girder segments, 164 piles (1.8m diameter), 96 cables on four pylons.
  • Eighth extra-dosed cable-stayed cum-balanced cantilever bridge approved by MoRTH in India.
• Approach Roads: 1 km on Sagara side, 3 km towards Sigandur

Why Was This Bridge Needed?

For decades, the Sharavathi reservoir (formed in the 1960s) submerged vast stretches of land, isolating villages and pilgrimage sites. Residents relied on a daytime-only barge service, which was inconvenient and unsafe, especially during emergencies or at night. The demand for a bridge intensified after tragic accidents and growing traffic, particularly from devotees visiting the famous Sigandur Chowdeshwari Temple.

Impact on Connectivity and Daily Life

• Travel Time: Reduces travel by more than 30 kilometers and cuts journey time by up to two hours for many residents and pilgrims.
• Tourism: Boosts access to major temples like Sigandur Chowdeshwari and Kollur Mookambike, encouraging tourism and local business.
• Economic Growth: Facilitates the movement of goods and services, supporting economic development in Sagar and Hosanagara taluks.
• Safety: Provides a safe, reliable alternative to ferries and coracles, especially during emergencies

Engineering and Construction

• Builder: Dilip Buildcon Ltd, Madhya Pradesh.
• Construction Timeline: Sanctioned in March 2019, construction began in December 2019, and completed in 2025.
• Innovation: Combines cable-stayed and balanced cantilever techniques, ensuring stability and durability

Community and Political Significance

The bridge’s inauguration is the result of persistent efforts by local residents, activists, and political leaders. It symbolizes progress and the fulfillment of a decades-long aspiration for better connectivity. The event was attended by Union Minister Nitin Gadkari and several dignitaries, marking a major milestone for Karnataka’s infrastructure.

The opening of India’s second longest cable-stayed bridge in Sagar marks a new era for the region. It stands as a testament to engineering excellence and the power of community advocacy, promising a brighter, more connected future for Karnataka.
