The bridge crosses the Kaoh Pao river, linking the province capital of Khemarak Phoumin (also known as Koh Kong City) to Pyam, near the Thai border. It was the longest bridge in Cambodia at 1900 metres, and it was inaugurated in April 2002. Koh Kong Bridge is an important part of National Road 48 (NR 48), linking Koh Kong Province to the capital of Phnom Penh. In a larger scheme, the bridge also finalised a long land transport route, connecting Thailand with Vietnam.
