Question

In cities flyovers are constructed with large sheets of fibre glass on the outer side of the flyovers. Give reason.

Answer 1

Flyovers in cities are constructed with large sheets of fiberglass on the outer side to reduce noise pollution. The fiberglass sheets act as sound barriers, absorbing or reflecting the noise generated by vehicles on the flyover. This helps in minimizing the impact of traffic noise on surrounding residential areas and improving the quality of life for people living nearby.
