Facing heavy traffic on the Chennai‑Trichy‑Madurai National Highway, repair crews are operating round‑the‑clock in two shifts. The goal is to finish before the festive travel rush.

  • More than 50% of repair work on Cauvery bridge completed
  • Two‑shift, 24‑hour operation aims for mid‑October finish
  • 120 bearings, 14 pillars, 16 expansion joints undergoing overhaul

Bridge History and Current Status

Constructed in 1963, the old Cauvery bridge on the Chennai Bypass is part of the NHAI‑managed Chennai‑Trichy‑Madurai corridor. After its last overhaul in 2010, the structure now faces a ₹10‑crore renovation to meet modern traffic demands.

Scope of Work

The project involves replacing 120 bridge bearings, strengthening 14 support pillars, repairing 16 strip‑seal expansion joints, and executing structural reinforcement measures. To date, 60 bearings have been swapped, with the remaining slated for the next 15 days.

Traffic Management

The bridge was closed on June 25, and traffic was diverted via the opposite carriageway between Sanjeevi Nagar Junction and Kondayampettai, minimizing commuter disruption.

Water Flow and Work Continuity

Delayed irrigation has left the Cauvery dry, granting NHAI a valuable window to complete work. Contingency plans are in place to keep construction uninterrupted even if water is released from the Mettur Dam.

Why This Matters

BozokMedia analysis shows that the timely completion of the Cauvery bridge repairs will significantly reduce congestion on one of South India's busiest corridors, boosting logistics efficiency and supporting the upcoming festive travel surge.

"The structural integrity of this bridge is critical for the resilience of the national highway network," said senior engineer Rajesh Kumar.
Did You Know?: The original bridge was inaugurated in 1963 and remains a vital crossing over the Cauvery River, linking key industrial hubs in Tamil Nadu.
