The net of highways extends in all directions. It meets Andun highway to northeast and Liudun highway to northwest, connects No.312 national highway at Anxi and Liuzhou, and leads to the cities of Jiayuguan, Lanzhou, Xi'an, Hami, Tulufan, Urumqi, etc. Extending southward, Liudun highway meets No.215 and 109 national highways, which leads to Germu of Qinghai Province and Lhasa of Tibet respectively. They are lifelines for entrance to Qinghai and Tibet before Xi'an-Germu railway opens. As the straight and wide asphalt roads within Dunhuang leads to all scenic spots, the traffic becomes very convenient.
