With Phnom Penh having outgrown its First Ring Road and the Second Ring Road due to open in 2019, the government is making plans for an even grander Third Ring Road that will encircle the the capital and ease traffic congestion. The proposed 47-kilometre road will be the outermost concentric circle around the capital, allowing vehicles to travel from one outerlying area to another without having to pass through the city itself.

According to Kong Sophorn, deputy governor of Kandal province, the Third Ring Road will form a semicircle that starts at National Road 4 west of the capital and arcs south and east to National Road 21 before crossing the river and heading northwards to connect to National Road 1. Overpasses will be built to cross National Road 4, 3 and 21, and a 25-metre-long bridge will span the Bassac River in Sa’ang district.https://www.phnompenhpost.com/supplements-post-property/third-ring-road-draft-plans-revealed
