The Tumen River Bridge crosses the Tumen River and links the road route between Hunchun City in China and Wonjong-tong, Sonbong in North Korea.
Sonbong is North Korea's rail link to Russia. A rail bridge crosses the Tumen River between the border rail stations of Tumangang Workers' District, Sonbong, and Khasan, Russia. This connection lies on one of two proposed paths for linking South Korea by rail to the Trans-Siberian Railroad and the rest of Eurasia, the other being through Sinuiju. The rail link through Sonbong is lightly used, carrying only 10,000 passengers in 2005.
In 2025, it was reported that North Korea and Russia had begun laying the foundations for a new road bridge a short distance downriver from the Korea Russia Friendship Bridge. The road bridge was opened on 7 September 2026 as the Yakov Novichenko Bridge, named for the Soviet military officer Yakov Novichenko, who shielded North Korean leader Kim Il Sung from an assassination attempted in 1946.
Sonbong is one terminus of the Hambuk Line railroad. It is also served by roads.
There is a seaport and a wharf at Sonbong Port.
