The First Thai–Lao Friendship Bridge is a vital international crossing over the Mekong River, linking Nong Khai Province, Thailand, with Vientiane, Laos. Opened on April 8, 1994, it was the first bridge to connect the two nations, significantly boosting trade, tourism, and diplomatic relations. Funded by Australia, the 1,170-meter-long structure accommodates both road and rail traffic, featuring a single railway track that extends the Bangkok–Nong Khai railway to Thanaleng Station in Laos.
