The pre-feasibility study was carried out in 1992, five alternative traces have been studied. In 1999 a Feasibility Study was carried out under grant aid assistance from government of Japan. After the Environmental Impact Assessment was conducted the project approval was obtained from Central Environmental Authority for the section from Kerawelapitiya to Kottawa for a length of 28 km. Detailed Design Study for this 28 km stretch was commenced in July 2001 under a grant aid assistance from Government of Japan. Basic Design of the project has been carried out. The project was delayed in November 2001 due to protests by residents in the area and the government decided to resettle them in different lands in the same area away from the planned highway. == Construction ==
