The worst affected stretch on National Highway-8 towards Gurgaon was clogged by miles-long tailbacks of thousands of vehicles forced-stuck in the jam that began late last evening.
As heavy rains lashed the capital, traffic was thrown out of gear with vehicles moving at snail's pace on waterlogged stretches, troubling office-goers and other commuters.
In a report on waterlogging and roads leading to NH-8, Delhi government said there was free flow of water in Najafgarh drain while the three drains pertaining to Haryana government - Bajghera, Dharampur and Badshahpur - that discharge water from Gurgoan into NG drain, were found to be under construction, which led to waterlogging.
Morning showers slowed the traffic on the capital's arterial roads. Waterlogging on roads and underpasses resulted in massive jams on several stretches, holding up commuters.
