Agreed, but the lanes are not wide enough. They should have had 3 lanes to allow heavy vehicles to run on, people find it hard to overtake them on the Colombo-Negombo road as it is. Moreover these vehicles should not be traveling at 100kmph+, & some of them are in pretty bad state & don;t even have working indicators or brake lights so they should be checking their road worthiness prior before being allowed on, which is highly unlikely. The idea of a 40ft container fishtailing at high speed or not being able to slow down in a hurry doesn't sound too appealing. They should be allowed on, but to run at slower speeds. This would still make the journey faster than the normal routes as the speed would be constant.
