The Southern coastal railway line from Galle to Kalutara South is to be shut down from July 1 to seven months.
The Ministry has said the railway line would be closed to carry out the second phase of the construction work on the Southern railway line.
The Southern coastal railway line is being upgraded and the railway line between Galle and Matara was upgraded under the first phase of the programme.
From July 1 trains would ply only up to Kalutara South and a fleet of buses in the area is to be increased and that measures would be taken to ensure adequate transport services for the people.
The Transport Ministry has said the Indian Railway Construction Company Limited is carrying out the upgrading work on the Southern coastal railway track and the stretch from Galle to Kalutara South has been estimated to cost US$ 42 million.
The entire project would cost US$ 167.4 million.
