Thailand’s Cabinet approved financial assistance for the Lao government to construct the Xiengman-Luang Prabang Mekong Bridge, Thai authorities announced on 8 September through the government’s Public Relation Department website.
Construction is expected to begin by 2027, run for approximately four years, and the bridge is projected to enter official operation by 2031.
Xiengman sits in Chomphet district, the only district of Luang Prabang Province located on the opposite bank of the Mekong from the town. Chomphet borders Xayabouly, which connects onward to Thailand’s Nan Province, making the bridge a key link in that border corridor.
Thailand’s Cabinet directed the national aid agency, Neighboring Countries Economic Development Cooperation Agency (NEDA), to provide Laos with THB 1.78 billion (USD 55.4 million) in financial assistance for the project, following a 2025-proposal from Thailand’s Ministry of Finance.
Boosting trade, tourism, and regional links
Once completed, the bridge is expected to cut travel time between Nan Province and Luang Prabang by 30 to 45 minutes, from the current roughly nine hours.
The bridge also complements Luang Prabang’s own infrastructure push.
In September 2025, Luang Prabang authorities launched an 80-kilometer ring road connecting Luang Prabang with Chomphet district at a signing ceremony, aiming to skip the UNESCO town area..
Further afield, the project extends NEDA’s broader footprint in Laos, which includes the 5th Lao-Thai Friendship Bridge between Bolikhamxay and Bueng Kan provinces, opened in late 2025, and upgrades to National Road 12 in Khammouane Province linking Thailand via the 3rd Lao-Thai Friendship Bridge to Vietnam’s Naphao border crossing.
