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.
On record
The official record states: "Highway officials admitted the substation relocation should have been arranged during initial design; a resident leader called officers "lethargic.""
Filed as "Under repeat delay (decades-long partial construction)" and dated to Sanctioned 2001; phased completion through 2023, this entry sits under the "Original ₹86 crore (2001); ballooned past ₹200 crore in later phases" 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.
