Photo taken on July 28, 2019 shows the closed Luang Prabang Mekong River Super Major Bridge in the north of the Luang Prabang Ancient Town, a world heritage, some 220 km north of the Lao capital Vientiane. With the concrete beam of the last span over Mekong River put in place, the main section of Luang Prabang cross-Mekong River railway bridge has been completed on Sunday, seven months ahead of schedule. The closure of the Luang Prabang Mekong River Super Major Bridge, one of the two cross-Mekong bridges along the China-Laos Railway, indicated that the railway project construction has made major progress in the 2019 civil engineering schedule.
