On July 16, 2025, Union Minister for Road Transport and Highways Nitin Gadkari inaugurated the Sigandur Bridge, India’s second longest cable-stayed bridge, in Shivamogga, Karnataka. Stretching 2.44 km across the Sharavathi backwaters in Sagar taluk, this ₹473 crore marvel, also known as the Ambaragodlu-Kalasavalli Bridge, is a triumph of engineering and regional development. Named after Goddess Chowdeshwari Devi, it restores connectivity lost after the Linganamakki dam submerged roads in the 1960s. X posts are abuzz, calling it a “game-changer” for Karnataka’s Malnad region.
- nauguration Date: July 16, 2025, by Union Minister Nitin Gadkari.
- Location: Spans 2.44 km across Sharavathi backwaters in Shivamogga.
- Cost: Constructed at ₹473 crore, a boost for regional infrastructure.
Boosting Connectivity and Pilgrimage
- Route Impact: Connects Sagara to Marakutika, cutting travel time by 2 hours.
- Temple Access: Eases access to the revered Sigandur Chowdeshwari Temple.
- Replaces Ferries: Ends reliance on barges, reducing wait times for devotees.
The Sigandur Bridge slashes travel distance by over 30 km, linking Sagara town to Marakutika and surrounding villages. Previously, devotees visiting the Sigandur Chowdeshwari Temple faced 3-hour barge waits or an 80 km road detour. Now, the bridge, built on NH-369E, offers seamless access, cutting travel time to the temple and nearby areas like Kollur by nearly two hours. This aligns with Swadesh Darshan 2.0, boosting sustainable tourism in Karnataka’s pilgrimage hubs. X users hail it as a “boon for devotees,” enhancing both convenience and regional tourism.
Engineering Marvel: Design and Features
- Structure: Extradosed cable-stayed with 740 m of cable support.
- Specifications: 2.44 km long, 16 m wide, with two lanes and pedestrian footpaths.
- Construction: Features 604 box girder segments, 164 piles, and 96 cables on four pylons.
The Sigandur Bridge is an extradosed balanced cantilever bridge, Karnataka’s longest inland crossing. Spanning 2.44 km with a 740 m cable-stayed section, it features a 16 m wide deck (11 m carriageway plus footpaths). Built with 604 box girder segments, 164 piles, and 96 cables anchored on four pylons, it supports vehicles up to 80 tonnes. Initiated in 2018 by Gadkari, with contributions from B.S. Yediyurappa and MP B.Y. Raghavendra, the bridge cost ₹378.3 crore for construction within a ₹473 crore project. A true engineering feat, as praised by retired NHAI engineer Peer Pasha
Political Tensions and Naming Controversy
- Congress Boycott: CM Siddaramaiah skipped the event, citing lack of prior consultation.
- Naming Debate: BJP proposes “Siganduru Chowdeshwari Bridge”; petition suggests “B.S. Yediyurappa Bridge.”
- Attendees: Union Minister Pralhad Joshi and B.S. Yediyurappa present, no state cabinet members.
The inauguration wasn’t without drama. Karnataka CM Siddaramaiah and his cabinet boycotted the event, alleging they received the invitation only on July 11, 2025, just three days prior, violating protocol. Gadkari countered, stating invites were sent and virtual participation offered. X posts reflect the spat, with some calling it “political drama.” A naming controversy also brews: the BJP named the bridge after Goddess Chowdeshwari, but a petition by Harinath Rao pushes for B.S. Yediyurappa’s name, crediting his advocacy. The Karnataka High Court will decide.
Historical Context and Regional Impact
- Linganamakki Dam Impact: Submerged roads in the 1960s, forcing reliance on ferries.
- Tragic Catalyst: 2017 boat capsizing (21 deaths) spurred bridge demand.
- Economic Boost: Enhances Malnad’s tourism and local economies.
The Linganamakki dam in the 1960s cut off road access, leaving villagers and devotees dependent on ferries or long detours. A tragic 2017 boat accident killing 21 people amplified calls for the bridge, a demand echoed by leaders like Kagodu Thimmappa and Yediyurappa. The Sigandur Bridge now restores connectivity, boosting tourism to the Chowdeshwari Temple and local economies in Sagar and Hosanagara taluks. With Karnataka’s highways expanding from 6,707 km in 2014 to 9,424 km in 2025, this bridge is a cornerstone of GatiShakti infrastructure goals.
