Kerala State Transport Project (KSTP) is one of the important and successful endeavours of Government of Kerala (GoK) and Public Works Department (PWD) implemented with the assistance of the World Bank (WB).

The reference to conceiving of this project goes back to 1996; by then GoK-PWD evaluated the lower efficiency of major road network due to rapid growth in traffic levels coupled with existing inadequate and deteriorating road infrastructure. To this respect the ‘Strategic Options Study’ (SOS), was carried out in 1997 covering nearly 9000Km of roads for prioritisation.

This important study based on strategic parameters recommended a priority list of road corridors for further techno economic feasibility study and then Detailed Engineering. 

In the year 1999, 2810 Km of roads recommended through SOS study were selected for Techno-Economic feasibility. Road Maintenance Component prioritisation and Institutional Development Strategy Studies were initiated in 2000.
