Route 450 (also known as 450 Year Road; Lao: ເສັ້ນທາງ 450 ປີ), is a highway in Vientiane Prefecture, Laos. It connects the Dongdok intersection in Xaythany district to Dongphosy in Hadxayfong district, near the First Thai–Lao Friendship Bridge, and forms part of the AH12 connecting Nateuy, Vientiane, and the Thai border at Thanaleng.

History

The road was first proposed in 1991 by the Vientiane Prefecture government as part of a plan for the city's economic and urban development, intended to link the planned Thai-Lao Friendship Bridge with the national highway network on the eastern side of the capital city.[1]
