The Ministry of Public Works and Transport issued a September 30 announcement detailing the conditions for use of the rest stops on the Phnom Penh-Sihanoukville Expressway, with the Chinese company-built road set to be opened for free for the month of October. The ministry said the expressway has four rest stops, each of which offers a parking lot, petrol station, public bathrooms and a canteen. Two of the four locations are in Kampong Speu province (40km) and in the west of that province (63km). The two others are in Preah Sihanouk province's Kampong Seila district (109km) and in the west of the province's Prey Nob district (156km). The expressway is constructed by Phnom Penh-based Cambodian PPSHV Expressway Co Ltd – a subsidiary of China Road and Bridge Corporation (CRBC) – with supervision by Malaysian firm Minconsult Sdn Bhd, at a cost of just over $2 billion. It stretches over 187km and runs through Kandal, Kampong Speu and Koh Kong provinces. The ministry reminded road users to respect traffic laws and use the road responsibly.
