Atal Setu, which has been built at a cost of over Rs 17,800 crore, is 5.5 kms on land and 16.5 kms over the sea. Atal Setu will contain a six-lane highway (3+3 lane) with one emergency lane on both sides. Over 70,000 vehicles are expected to use Atal Setu every day, and the travel time is likely to be reduced from 1.5 hours to just 20 minutes.
