The rehabilitation and upgrading of about 10,000 kilometres of existing national highways to a four lane dual carriageway configuration on a Build Operate Transfer (BOT) basis is proposed under phase III of the Project.

If traffic needs to be closed or a carriageway is occupied for a long time due to the maintenance project, except for emergency situation, the management and maintenance unit shall issue to the public the information of construction and traffic control together with the traffic police department 15 days ahead of time.

The street trees have really four jobs to do and that's it To spatially denote the pedestrian realm, to protect the pedestrians from the vehicles in the carriageway, to filter the sunlight onto the sidewalk, and to soften the hardscape of the buildings and to create a ceiling a vaulted ceiling over the street, at its best.
