Asian Highway 3 (AH3) is a route of the Asian Highway Network which runs 7,331 km (4,555 mi) from Ulan-Ude, Russia (on AH6) to Tanggu, China; and Shanghai, China (on AH5) to Chiang Rai, Thailand and Kengtung, Myanmar (both on AH2).
By mid-2008 the North-South Corridor segment of the Asian Highway, AH-3, was nearly fully paved, with only a few kilometers incomplete.
The North-South Corridor Project has been part of the Asian Development Bank's (ADB) agenda since 1993 and aimed to improved the connected economies of China, Myanmar, Laos, Vietnam, Thailand and Cambodia. The portion of the North-South Corridor known as Highway 3, which runs through northwestern Laos and connects China and Thailand, was expected to cost US$95.8 million and was being financed with a loan from the ADB, along with funds from the Chinese, Thai and Lao governments.
The completed sections of the road have gone from being little more than dirt roads a few years ago to two-lane routes with concrete shoulders, drainage and concrete bridges. The journey from the Lao border town of Huai Xai to the southwestern Chinese border village of Boten situated in southwestern Yunnan province took as long as two days on the old mostly dirt road depending on weather conditions. The new roadway shortened that trip to five to six hours.
The route was expected to be completed in 2007, but damage to the road from floods during the 2006 rainy season pushed the completion date into 2008. While the road was now made passable all year, there are still sections, some of several kilometers in length, which remained unfinished as of 2008.
Construction of the Thai-built portion of the road lagged behind that of the Chinese section, but some observers contend that was because the Thai section was "much better constructed". They indicated that the Chinese side was built faster because of engineering shortcuts which may make that section of the road less durable.
