The two countries will hold an opening ceremony to mark the official opening of the New Yalu River Bridge, Chinese state news agency Xinhua reported on Wednesday morning.
Last week, signs that the bridge would soon open were spotted, including vehicles crossing and traffic lights and bridge indicators being activated, according to South Korean newspaper The Chosun Daily.
The bridge links the Chinese city of Dandong with Sinuiju and is expected to become a major trade route between the two countries.
