Even though the overall road density is high in Sri Lanka relative to other developing countries, the condition of C class and B class roads are mostly not in good condition. Those roads are occasionally not wide enough for buses as well.

The main reason is that the roads reach its maximum capacity during the peak hours causing heavy traffic. When considering the expressways, as they were built very recently condition is good and assure a fast and smooth journey. In order to maintain the surface quality periodic maintenance is expected. Currently few new development projects are under progression in the Paliyagoda area. A new bridge was developed and opened recently in Rajagiriya increasing the capacity of the roads, due to the vehicle flow. Therefore has reduced the traffic relatively and allows smooth flow of vehicles.
