The Vientiane-Vangvieng highway will be part of the mega Laos-China Highway Project which will stretch between Vientiane and Boten in Luang Namtha where the Laos-China border is located.
The Vientiane-Vangvieng highway will stretch 113.5 km between Vientiane and Vangvieng district, Vientiane Province.
It is designed to be 23 m wide with 4 lanes, two incoming and outgoing. At a cost of around US$ 1.3 billion, the highway will be built between Sikeuth in Naxaythong district in Vientiane and eastern Vangvieng from which the next phase of the Laos-China highway project will be connected.
The highway will run in parallel with existing Road 13 North through Naxon, Boua, Saka, Phonhong, Nongkhay, Phoupha, Hinheub, Vangkhi, Thaheua villages.
The road is designed to withstand a max speed of 80 km per hour. Seven roundabouts will be built along the highway along with two service areas and two rest areas. The service facilities will be equipped with gas stations, hotels, shops, restaurants and garages.
The project will be conducted as a Build-Operate-Transfer (BOT) project by Yunnan Construction Engineering Group. The construction of the highway was originally scheduled to take place in November 2017 and be completed in 2020.
