The Mumbai Trans Harbour Link (MTHL) is set to shorten travel time between Mumbai and Navi Mumbai to 20 minutes, and will also enable connectivity to the Third Mumbai or the Navi Mumbai Airport Influence Notified Area (NAINA). The project, developed by the City and Industrial Development Corporation (CIDCO), is a well-planned city with ultra-modern facilities in an area of 371 sq. km around the Navi Mumbai International Airport. The Third Mumbai was announced in 2013 to prevent haphazard growth of the upcoming airport area.
