On record

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.

The official record states: "Highway officials admitted the substation relocation should have been arranged during initial design; a resident leader called officers "lethargic.""

“Twenty-three years, held up by a substation nobody thought to move in 2001.”— Blunderlust Editorial Desk

Thiruvanmiyur–Uthandi ECR Elevated Corridor Suspension

A planned four-lane elevated corridor along ECR between Thiruvanmiyur and Uthandi, awarded via a Hybrid Annuity Mode concession to KNR Mahabalipuram Infra Private Limited in February 2026, was put on hold pending review by a technical committee after being conspicuously omitted from Tamil Nadu's 2026-27 Highways policy note. A rival bidder had also filed a procurement challenge in the Madras High Court.

Manapakkam Metro Girder Collapse

On the night of June 12, 2025, a 40-foot concrete I-girder under construction for Chennai Metro Phase 2 collapsed from over 20 feet height after its supporting A-frame gave way, crushing a motorist, C. Ramesh (43), to death. It took rescue teams over five hours to retrieve his body from under the girder. Police booked contractor L&T and four of its officials under BNS Section 105 (culpable homicide not amounting to murder).

Tambaram (Irumbuliyur) Flyover Cave-in and Cracks

In April 2025, a section of the road surface on the 2012-built Irumbuliyur/Tambaram flyover on GST Road caved in, and a crack was simultaneously found on the flyover's railing wall near its starting point. Just 13 years after construction, the structural deterioration alarmed residents and commuters, prompting police to barricade the area and divert traffic while emergency concrete repairs were carried out.
