As of today, Oct 15, there is no public official technical inspection report, lab test result, or KMC / KMDA specification sheet confirming the exact material used on the flyovers.
Here's what is on record so far about the Chingrighata incident:
What happened:
Three motorcycles skidded one after another on the freshly painted Chingrighata flyover on Oct 14, midday during rain, while negotiating a bend. The dashcam video from a following car went viral. Similar skids were also reported on Gariahat flyover after rain.
What was painted:
The carriageways of Chingrighata, Gariahat, and a stretch of Red Road were painted in rainbow / VIBGYOR colours ahead of Durga Puja as a beautification drive.
Media reports allege enamel paint, which lacks anti-skid properties, was used instead of ideal thermoplastic material.
Official position vs technical gap:
âĸ Urban Development Minister Agnimitra Paul said the paint was "anti-skid" and done keeping safety guidelines in mind, and that it is not permanent and will wear off in a few months and. She also said no taxpayer money was used, it was done through CSR.
âĸ CM ordered a probe, tasking Kolkata Police Commissioner to examine the matter.
âĸ Environmentalist Somendra Mohan Ghosh, who wrote to the minister, pointed out that roads should follow IRC:35-2015 - Code of Practice for Road Markings, which recommends thermoplastic materials, not glossy oil paints, because glossy paint forms a smooth film and friction coefficient drops sharply when wet and.
But no municipal lab report, skid-resistance test value, friction coefficient, or product specification sheet has been released to the press so far.
PTI itself noted it could not ascertain the veracity of the viral videos, and the minister said "circumstances are being investigated".
public debate is running on dashcam footage and statements, not on an official technical inspection.
If you're riding that stretch â especially in rain â avoid the painted wheel-track area, keep speed low on the bend, and increase following distance. The painted surface is visibly glossy when wet.
