Fourth Thai–Lao Friendship Bridge

[2][4] It is about 10 kilometers from Chiang Khong District in northeastern Chiang Rai Province, in northern Thailand, and about 12 kilometers from Houayxay, the capital of Bokeo Province, northwestern Laos.

[2] In the south, a three kilometer service road connects the bridge to the Chiang Khong-Thoen Highway and Route 1129 in Thailand.

The project was hoped to boost trade and development of the Greater Mekong Subregion.

On 12 December 2012, a ceremony marking the joining of the two sides of the bridge was held in Houayxay, Laos.
