The Nam Heuang Thai–Lao Friendship Bridge is the only permanent border checkpoint in Loei Province that connects to Xayaboury Province, Lao PDR. It crosses the Nam Heuang River, a natural boundary between the two countries. The bridge, built as a single-lane concrete structure, spans about 110 meters and was officially opened in 2004.

This bridge plays a significant role in boosting trade, tourism, and cultural exchange in Thailand’s upper northeastern region. It serves as the shortest transportation route from Loei to major destinations in Laos, including Kenthao in Xayaboury Province, and onward to the UNESCO World Heritage City of Luang Prabang via Lao Route 4.

Visitors can cross the border using a passport or obtain a temporary border pass. On the Lao side (Kenthao), there are local markets and duty-free shops where travelers can explore and shop for local products.
