A bridge connecting Russia and North Korea by road for the first time marked an "historic event," Russian Prime Minister Mikhail Mishustin said in a speech on Monday.
Mishustin said in a statement that construction of the bridge, which is one kilometre long, had been completed in 16 months.
The bridge over the Tumen River can handle up to 300 vehicles per day and will connect North Korea to Russia's international "West-East" transport corridor, which runs from Vladivostok to St Petersburg in north-western Russia.
Moscow and Pyongyang agreed to build the bridge in 2024. Before that, the two countries were connected by land only by a railway bridge that opened in 1959. Russia and North Korea share just over 17 kilometres of land border, running along the Tumen.
North Korea is an important ally of Russia in its war against Ukraine, which began in 2022. Pyongyang supplies Russia with ammunition and has sent up to 15,000 soldiers to support Moscow in the war in Ukraine, according to estimates by South Korea's intelligence service.
