Post-war development in the Colombo area also involves the construction of numerous expressway grade arterial road routes. The first of these constructed is the Southern Expressway, which goes from Kottawa, a southern suburb of Colombo, to Matara City in the south of the country. Expressways constructed in the Colombo metropolitan area include the Colombo–Katunayake Expressway, which was opened in October 2013 and the Colombo orbital bypass Outer Circular Highway (Arthur C. Clarke Expressway). The Colombo-Katunayake Expressway (E03) runs from Peliyagoda, a northern suburb of Colombo, to Colombo International Airport and it linked with one of the major commercial hubs and a major tourist destination of the country, the city of Negombo.
