"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.
