The Southern highway project in Sri Lanka is a 126km-long express highway running from Colombo to Matara on the south coast. The project is a major part of the 130.9km Southern Transport development project.

The Southern Highway project was divided into two sections for financing purposes. The first section consists of the expressway from Kottawa (a suburb in Colombo) to Kurundugahahetekma. The second section consists of the long expressway from Kurundugahahetekma to Matara.


The southern region of Sri Lanka will become easily accessible once the project is completed. The project will increase road safety and the travel time between Colombo and Matara will be greatly reduced.

The project was initially estimated to cost $348.75m, but escalated to $741.1m. Construction was started in 2003 and the project was anticipated to be completed by 2010. It has, however, been delayed to mid-2011 as negotiations are ongoing between the Government of Sri Lanka (GOSL) and the Export and Import Bank of China, regarding the financing of section four.

Planning and design

"Construction was started in 2003 and the project is anticipated to be completed by mid 2011."
The expressway between Kottawa and Kurundugahahetekma is 66.5km long. The section is divided into two parts: package I and package II. Package I comprises the road from Kottawa to Dodangoda (35km) and package II is from Dodangoda to Kurundugahahetekma (31.5km). The road in package I was originally planned to be a four-lane road and package II a two-lane road. However, while implementing the project, a decision was taken that the entire expressway should be a four-lane road structure, with phase II expanded from the planned two lanes.

The project's second section involves construction of a 59.5km-long four lane road between Kurundugahahetekma and Matara.

The speed limit of the express highway is 120km/hr. Once the project is finished, the travel time between Colombo and Matara will be reduced from four hours to 1.5 hours.

Financing

The project is being financed by Japan Bank for International Corporation (JBIC), the Asian Development Bank (ADB) and the Government of Sri Lanka (GOSL). JBIC provided a loan of $2.05bn, while ADB and GOSL provided $1.03bn and $1.26bn, respectively.

JBIC's loan is availed for the 66.5km-long first section expressway from Kottawa to Kurundugahahetekma while ADB is funding the 59.5km-long second section expressway from Kurundugahahetekma to Matara.

Construction

Construction commenced on the ADB-funded section in April 2003. Package I in the other section commenced construction in September 2005 whereas package II commenced in March 2006. The Ministry of Highways of Sri Lanka is the executing agency of the project whereas the Road Development Authority is the implementing agency.

"The project was initially estimated to cost $348.75m, but escalated to $741.1m."
The intersections on the Colombo-Matara expressway include Kottawa, Baddegama, Kahatuduwa, Pinnaduwa, Gelanigama, Deegoda, Dodangoda, Kokmaduwa, Welipanna, Godagama and Kurundugahetekma.

The majority of the construction work of the ADB-funded section of the project such as construction of bridges, tunnels and earth fillings were completed by September 2009. Works on the section were fully completed by August 2010.

Bridge construction

A total of 22 bridges are being constructed along the expressway. As of 2009, three bridges have opened: the Kalu Ganga bridge, the Welipenna Bridge and the Benthara Ganga bridge. These bridges were opened in part to mitigate flooding in their respective areas.

Contractors

The ADB-funded section or the road from Kurundugahahetekma to Matara Godagama was contracted to Kumagai Gumi of Japan. The contractor was selected by the Road Development Authority of Sri Lanka in December 2002. Under the contract, Kumagai has to build a 29km-long express highway, a 5km access road and 16 bridges.

The supervision consultants in the section are Halcrow Group with Roughton International and Engineering Consultant.

Package I of the section was contracted to China Harbor Engineering Company while package II was contracted to Taisei Corporation of Japan. The civil works contractor pre-qualification was completed in March 2003. In March 2004, bid documents were issued to the prequalified contractors and the bids were closed in June 2004.

The supervision consultants are Pacific Consultant International with Resources

CCTV

The first phase of the southern highway from Colombo to Galle which will be opened in August will be installed with CCTV cameras to keep a tab on errant motorists, RDA Director General R.W.R.Premasiri said.



He said that the cameras are intended mainly to monitor speeding, "The speed limit on the highway is 100 kilometres per hour and we have to ensure that motorists don’t exceed this and thereby cause accidents," he said.
