Kochi's Varapuzha Bridge Opens to Traffic, Alleviating Long-Standing Congestion
The newly constructed Varapuzha bridge, the largest structure on the Edapally–Moothakunnam stretch of National Highway 66 in Kochi, has been officially opened to traffic. This development is expected to significantly ease the persistent traffic congestion that has plagued the region for years. The bridge, a balanced cantilever structure spanning the Periyar River, measures 1,026 metres in length and was built at an estimated cost of Rs 100 crore over 604 days.
Technical Details and Construction Method
The Varapuzha bridge features 26 spans, with a central span of 120 metres designed to provide ample clearance for vessels, ensuring uninterrupted movement for Kochi Water Metro services, State Water Transport Department vessels, and local ferries. The construction employed the cantilever method, typically used for spans exceeding 50 metres. This technique involves building segments outward from piers while maintaining balance on both sides, culminating in the meeting of opposing arms at the centre.
"The cantilever method allows for a long central span, which is crucial for smooth navigation below the bridge," explained a senior official from the National Highways Authority of India (NHAI). "This ensures that water transport remains efficient and safe."
Delays in Broader Highway Widening Project
Despite the bridge's opening, the broader plan to widen the 26-kilometre corridor into a six-lane highway has faced further delays. The NHAI has revised the project deadline from August 2026 to December 2026. Originally scheduled for completion in December 2025, the Rs 1,618-crore project is already behind schedule due to multiple challenges.
A shortage of red soil for land-filling stalled work for nearly a year, pushing the initial target to August 2026. This issue was later resolved through an agreement with the Cochin Port Trust to use dredged soil from the shipping channel. However, additional delays have arisen from the inclusion of new infrastructure, particularly pedestrian underpasses along the corridor.
Infrastructure Progress and Future Plans
As part of the widening works, seven major and eight minor bridges are being constructed. All except those at Kottappuram and Moothakunnam have been completed. The Varapuzha bridge itself was finished three months ago but remained closed due to unfinished approach roads stretching 1,400 metres, which lie about three metres below the existing road level.
The bridge was finally opened on Sunday after a series of accidents caused by severe congestion at the construction site, highlighting the urgent need for relief. Originally slated for a May opening, the delay underscores the complexities involved in large-scale infrastructure projects.
Looking ahead, the NHAI plans to retain and renovate the old Varapuzha bridge to function alongside the new three-lane structure. New approach roads for the old bridge will be constructed after the current ones are dismantled, ensuring continued connectivity and efficiency.
This development marks a significant step forward for Kochi's transportation network, though the extended timeline for the full highway widening serves as a reminder of the hurdles in infrastructure development.
