A nearly one km-long stretch of the Mumbra bypass on the outskirts of the city caved in on Wednesday morning due to incessant rains and has been closed for vehicular traffic, police said.

“Due to heavy rains, around one km-long stretch of the Mumbra bypass has developed huge craters and has been badly damaged. As a precautionary measure, the traffic on either side of the road has been diverted”, a police officer said.

However, the closure of the bypass has led to traffic snarls in the internal parts of the city.

The Mumbra bypass on the National Highway 4 (Mumbai-Pune highway) is a crucial link to traffic from Delhi-Ahmedabad-Mumbai (NH3) and Agra-Nashik-Mumbai (NH8) going towards Panvel, Jawaharlal Nehru Port Trust (JNPT), Pune and beyond, and is mostly used by heavy vehicles.
