News

 

A 190 kilometer expressway project is set to link Phnom Penh to Sihanoukville. Cambodia’s Ministry of Public Works and Transportation reports that the project has reached 20% completion since construction began in March 2019.

Cambodia Prime Minister Hun Sen underscored that construction of the expressway is in line with regional integration in both the ASEAN and the Greater Mekong Subregion, linking regional transport networks from one country to another.

The expressway will promote reliability, safety, and mobility of Cambodia’s road network. It will allow the movement of a large number of vehicles and reduce the 5-hour travel time by 50%.

The Japan International Cooperation Agency (JICA) undertook the feasibility study for the development of the expressway in 2006–2018. It will be a two-lane road with a length of 190km, width of 24.5m, and a maximum speed limit of 100km/h. Sections of the expressway will run along National Road 4, one of the busiest roads in Cambodia, and help mitigate traffic.
