Bengaluru’s Silk Board Ramps of Double-Decker Flyover Turns Into Swimming Pool After 30 Minutes of Rain

The Double Decker Flyover near Silk Board in Bengaluru turned into a swimming pool after heavy rains on Monday evening. A viral video showed water gushing across the flyover, sparking outrage over poor workmanship and administrative negligence.

A city resident shared the clip on social media, highlighting the flood-like situation. Soon, criticism poured in about the design and faulty drainage system of the much-hyped flyover.

Citizens Question Drainage System

"This kind of situation happens when the drainage system is inadequate. The drains are only on one side," an X user commented.

Another user mocked, "Bengaluru's double-decker flyover floods after 30 minutes of rain. How does a flyover get flooded? This is an engineering marvel."

Many others joked that just 30 minutes of rain could convert Bengaluru's double-decker flyover into a swimming pool.

About Bengaluru's Double Decker Flyover

The 5.12 km-long double decker flyover, stretching from Ragigudda to Central Silk Board, is South India's first metro-cum-road structure. Built by the Bangalore Metro Rail Corporation Limited (BMRCL) at a cost of ₹449 crore, it has:

Four lanes of road traffic on the lower deck

Namma Metro Yellow Line on the upper deck

The flyover opened to the public in July 2024 to ease congestion at Silk Board, one of Bengaluru's busiest junctions. However, the 1.37 km-long connecting ramps to HSR Layout, Ragigudda, and BTM Layout remain incomplete.

Rainfall Exposes Engineering Flaws

Monday's rains, lasting less than an hour, exposed the flaws in the flyover's drainage.

Vidyapeeth: 34.5 mm

Kengeri: 33 mm

Rajarajeshwari Nagar: 32 mm

Other areas: 10-30 mm (KSNDMC data)

The incident has raised serious questions about BMRCL's planning and execution of the project, which was meant to reduce congestion but is now facing severe criticism.
