The ministries concerned will be required to complete the formalities for implementation of the projects in a time-bound manner and will also regularly monitor their progress, said a PMO statement.
The projects, for which implementation timeline has been finalised include two major ports in Andhra Pradesh and West Bengal and three airports at Navi Mumbai, Mopa (Goa) and Kannur (Kerala).
The other projects include elevated rail corridor project in Mumbai, high-speed rail corridor between Mumbai and Ahmedabad and other routes, and redevelopment of five railway stations.
"In recent meetings, detailed roadmaps have been worked for the flagship infrastructure projects in key sectors. These flagship projects had been identified and approved by the Prime Minister in the infrastructure meeting held on June 6, 2012", the statement said.
The detailed timelines for implementation of these projects, it said, "have been drawn up for intermediate stages. Mechanisms have also been put in place for regular monitoring and problem solving".
The speedier implementation of the key infrastructure sector projects is needed to promote investment and also boost economic growth which slipped to nine-year low of 6.5 per cent in 2011-12. MORE
