Thailand’s Department of Highways has opened the 21.8 km Nong Khai eastern bypass to enhance transport efficiency and support cross-border trade with Laos. The new route allows both freight and passenger traffic to bypass the congested town centre of Nong Khai, a key gateway for regional commerce.
Constructed with an investment of THB2.893 billion, the bypass connects Highway No. 2 (Mittraphap Road) and Highway No. 212, enabling smoother travel between Udon Thani, Nong Khai and Bueng Kan. Designed as a four-lane special-class highway, the project includes grade-separated interchanges, bridges, U-turn facilities, and road widening sections to improve safety and capacity.
The bypass is expected to significantly reduce travel time, ease congestion and improve logistics efficiency, particularly as trade, tourism and investment flows between Thailand and Laos continue to grow. It also strengthens connectivity to the First Thai–Lao Friendship Bridge, the main cross-border link to Vientiane.
