The Myawaddy-Thinggan Nyenaung-Kawkareik section of the Asian highway linking India, Myanmar and Thailand has been put into service, the media reported.
Myanmar Vice President U Nyan Tun, Thai Deputy Prime Minister Somkid Jatusripitak and Chairman of the Kayin National Union General Saw Mutu Sae Po attended an inaugural ceremony of the service on Sunday, Xinhua reported.
With the 25.6-km-long section becoming operational, travel time between Thinggan Nyenaung and Kawkareik will be reduced from three hours to 45 minutes.
The construction of the Asian highway section started in 2012 with the assistance of Thailand.
The Asian highway runs from Moreh in India to Thailand's Maesot via Myanmar's Tamu, Mandalay and Myawaddy.
The section, also part of the East-West economic corridor of the Greater Mekong Subregion, will not only enhance trade between Myanmar and Thailand, but also contribute to better links among people in the region.
A cornerstone laying ceremony was also held at Myawaddy on Sunday for the building of Myanmar-Thailand Friendship Bridge No.2 to link Thailand's Maesot with Myanmar's Myawaddy.
