They spent hours on the road on their way back home on Monday evening and were caught again in long traffic snarls when they returned to work on Tuesday.
Thanks to several waterlogged streets, Delhi witnessed yet another traffic jam on Tuesday morning.
According to senior traffic officials, the ITO Chungi underpass in East Delhi, Indraprastha flyover near ITO and the Dhaula Kuan underpass continued to be submerged in deep water, leading to traffic jams along several East Delhi, Central Delhi and South Delhi roads.
Debris from the Ring Road bypass construction site blocked the drains near the Indraprastha flyover near ITO.
Senior Public Works Department officials admitted their pumps had failed and rainwater could not be cleared from the ITO Chungi underpass till late Tuesday morning, leading to traffic jams.
While the road construction agencies are on a construction spree, building a number of new flyovers, underpasses and grade separators, they have failed miserably to provide proper facilities to ensure smooth flow of rainwater.
More than 100 traffic signals stopped working. The traffic police said extra staff was posted at junctions where the signals stopped working.
The traffic jam along Ring Road between ITO and North Delhi was so bad that a battalion of Commissioner of Police's reserve force had to be called in to tackle the situation.
The jam started from Shantivan and IP flyover and went ahead to choke all arterial roads of North Delhi, Old Delhi, ITO and Central Delhi.
"Normalcy could be returned after midnight at several points," the police officer said.
