CIDCO planned and constructed all the railway stations in Navi Mumbai and developed nearby areas commercially.
In 1973 the Creek Road Bridge, Vashi Bridge, was opened to the public for residents of Vashi, Belapur, and Nerul. The Sion Panvel Expressway was built to reduce the time taken to travel from Sion to Panvel. Initially there was not much response to the new city. Major changes took place only after 1990, with the commissioning of a wholesale agricultural produce market at Vashi and the construction of a commuter railway line from Mankhurd to Vashi in May 1992. These developments caused a sudden growth in economic activities and population in Navi Mumbai.
Recent developments
By the end of the 1990s, the planning authority of Navi Mumbai initiated private participation in the developmental activity of Navi Mumbai.
Some of the older and more populated nodes are Vashi, Nerul, and Belapur. Some of the more recently developed nodes include Kharghar, Kamothe, Koperkhairane, and New Panvel.
A new link between Nerul and Uran is under construction. Kharghar and Panvel are experiencing major infrastructural developments due to their proximity to the proposed Navi Mumbai International Airport
