Gurgaon: The Haryana government on Friday declared a two-day school holiday while the Gurgaon police issued an advisory to avoid travelling as thousands of commuters remained stuck on National Highway 8 due to flooding on the roads. "People coming to Gurgaon from Delhi are advised to stay back today to avoid being stuck in traffic jams due to flooding on roads," said Gurgaon Police on Twitter. It added: "Traffic situation in Gurgaon especially on NH8 and Sohna Road is congested and very slow due to rains and flooding. Avoid if possible." The traffic snarls in Gurgaon started when various roads in the city were flooded after heavy rainfall on Thursday. The traffic nightmare in the Millennium City was so worse that some of the commuters were stuck since Thursday evening. "I left my office at 7 p.m. yesterday (Thursday). I could only move 500 metres in five hours. Later, I decided to park my car on the road and went back to office," said an accounting professional Ajay Pratap who slept in his office on Thursday. The police have said that the traffic situation the city would not improve before noon.
