The Mumbai Trans Harbour Link (MTHL), also known as Atal Setu, the 21.8-kilometer-long bridge connecting Mumbai to Pune and the under-construction Navi Mumbai Airport, was inaugurated by Prime Minister Narendra Modi. Built at a cost of Rs 21,200 crore, the bridge will provide faster connectivity to Mumbai International Airport and Navi Mumbai International Airport, reducing travel time from Mumbai to Pune, Goa, and South India from two hours to 15-20 minutes.
