Road density is highest in the southwest, particularly the area around Colombo. Highways are in good condition, with a smooth [[bitumen]] surface and road markings; however, some rural roads are in poor condition. Heavily travelled roads are being upgraded and repaved. Public transport is widely available in many rural areas.<ref name=import>{{cite news|title=Sri Lanka Transport Board to import 2,000 single door buses for rural transportation|url=http://www.colombopage.com/archive_11B/Dec05_1323096445CH.php|access-date=2011-12-06|newspaper=ColomboPage|date=2011-12-05}}</ref>
