Roads are the dominant mode of transportation in Cambodia, accounting for 65% of freight movement and 87% of passenger’s traffic. Cambodia considers to develop two expressways in order to serve the growing extent of economy and trade. The project should start by 2020. The first line will lead from the capital Phnom Penh to the coastal Preah Sihanouk province with a total length of 230 km. The second one will lead from Phnom Penh to Ho Chi Minh City, Vietnam with a total length of 213 km.
Relating to the road transport, there are three competent authorities for the management of roads infrastructure:
The Ministry of Public Works and Transport (MPWT) is the competent authority for the transport sector in the Kingdom of Cambodia and manages the expressways, national roads, provincial roads. Under the MPWT there are two main Directorates related to national and provincial road transport.
The Ministry of Rural Development (MRD) is the competent authority to manage rural roads and other roads as assigned by the Royal Government.
The sub-national administration is the competent authority to manage roads within the capital, cities, provincial urban through the assignment of duties from the MPWT and the MRD and approved by the Royal Government.
