The Road Development Authority (RDA) yesterday said that the landslide mitigation work on the Kokmaduwa-Imaduwa stretch of the Southern Expressway (E01) would cost about Rs. 300 million.

RDA Southern Transport Development Project (STDP) Director E. H. Y. S. M. Garusinghe told The Island that the mitigation work would start in February and completed before June.

The National Building Research Organisation (NBRO) identified a landslide prone area near the 114 km post on a seven kilometre stretch between Imaduwa-Kokmaduwa of the Southern Expressway in October, last year.

The authority had already invited tenders for the mitigation design given by the NBRO, Garusinghe said.

According to the RDA’s Expressway Operation, Maintenance and Management Division, there were two landslide prone areas on the Southern Expressway in Welipenna and Kokmaduwa. The landslide mitigation work in Welipenna area has already been completed.

The division said that the mitigation work at Kokmaduwa would be conducted by the Southern Expressway Project.

Southern Expressway is 126.1 km long from Kottawa to Matara. The maximum operating speed for this section is 100 kmph. The original plan was to extend the Expressway to Hambantota to link the Mattala Airport and Hambantota Harbour to the Commercial Capital of Colombo.

The section of the Southern Expressway from Pinnaduwa (Galle) to Godagama (Matara) was opened to vehicle traffic on March 2014. The first section from Kottawa to Pinnaduwa (Galle) was completed in November 2011. The Asian Development Bank (ADB) and Japan Bank for International Corporation (JBIC) were the main funding bodies for the E01.
