The 1.15km Koyambedu flyover, inaugurated by CM M K Stalin, developed multiple potholes, exposed expansion joints and jutting-out steel reinforcement bars within about four years — a hazard flagged by cyclists and commuters.

On record

The official record states: "Not specified — no official cause for the premature deterioration has been publicly confirmed."

Filed as "Under repeat repair" and dated to 2021 (inaugurated November 2021), this entry sits under the "₹93 crore" line of the public accounts.

What to expect

  • Pillars reaching skyward with no deck to justify them.
  • A signboard promising an opening date that has since passed, unbothered.
  • Traffic queuing patiently beneath the unfinished span.
  • Rebar exposed where the road was meant to continue.

Perungalathur Flyover — 23-Year Construction Delay

First sanctioned in 2001, the flyover stayed incomplete for over two decades because an electricity board substation blocking the alignment was never relocated at the planning stage. Phase 3 only opened in June 2023, leaving roughly 200,000 residents to endure prolonged traffic chaos.
