Transport in Sri Lanka is mainly on the road network, which is centered in the Sri Lanka's capital, Colombo. There is also a railway network, but it only covers a small fraction of the country's transport needs. There are navigable waterways, harbours and two international airports located in Katunayakeand and Mattala. And there are domestic airports located in Rathmalana, Jaffna and Batticaloa. The highways and roadways around the country are in a very good condition and are being upgraded after establishment of peace in the country since 2009.
Road transport accounts for about 93% of the land transport in Sri Lanka. As of February, 2016, there are 12,210.36 km of A class and B class roads and 170 km of expressways15. The Colombo–Mataraexpressway is a 126 km long motorway, linking Colombo, Galle, and Matara. The Colombo-Katunayake expressway is Sri Lanka’s second express highway, which links Colombo with Bandaranaike International Airport,Katunayake and Negambo city. Other expressways are in the pipeline, while some are under construction.
The Colombo Outer Circular Expressway (also known as the Outer Circular Highway, Colombo Inter-provincial Orbital Router or the Arthur C. Clarke Expressway) is a highway in Colombo, Sri Lanka. It was opened in sections. The latest section between Kaduwela and Kadawathawas opened on 17 September 2015. The 29 km long outer circular road network links the Colombo - Mataraexpressway with Colombo - Katunayakeexpressway and the proposed Colombo - Kandy expressway and will provide an orbital beltway to bypass the city of Colombo and reduce traffic congestion.16
