Kolkata Roads: Concrete Blocks Used for Durable Repairs

Some roads in Kolkata keep getting damaged, especially after it rains.

The city is trying to fix them by using special concrete blocks that fit together.

They're putting these blocks on certain roads, like near the Howrah Bridge and Science City, to make them last longer.

But, experts say that it's important to fix the drainage problems so the blocks don't get ruined by water over time.

Also, they can be used on parts of roads but are not as smooth as the normal roads, and may make it harder for vehicles.
