Repair works on Cauvery bridge on in full swing
The National Highways Authority of India is conducting urgent repairs on the 1963-built Cauvery bridge on the Chennai-Tiruchi–Madurai National Highway. Work is proceeding around the clock to ensure completion by mid-October before the festival season.
Why it matters
Infrastructure maintenance is critical for maintaining supply chain efficiency and public safety on one of India's major national highway corridors.
More than 50% of the repair and maintenance works taken up on the old Cauvery bridge on the Chennai-Tiruchi–Madurai National Highway have been completed so far.
Built in 1963, the bridge situated on Chennai Bypass is undergoing extensive repairs at an estimated cost of ₹10 crore. It was closed on June 25 to facilitate repairs by the National Highways Authority of India’s concessionaire maintaining the section and traffic has been diverted via the other carriageway between Sanjeevi Nagar Junction and Kondayampettai.
The work includes replacing 120 bridge bearings, maintaining 14 support pillars, repairing 16 strip-seal expansion joints, and carrying out structural strengthening measures. The bridge was last repaired in 2010.
Given the heavy volume of traffic on the highway and the approaching festival season, the NHAI has expedited the work. At present, the works are under way round-the-clock in two shifts and are expected to be completed by mid-October.
