The 2,215-meter bridge will link the city of Tongjiang in China's Heilongjiang Province with Nizhneleninskoye in Russia's Jewish Autonomous Region.
China started constructing its segment in August 2014 and is now wrapping up the process, according to CCTV. The length of the Chinese segment of the bridge totals 1,886 meters.
The Russia-China railroad bridge is slated to be completed by June 2018. Once constructed, it will become the main channel of communication for the economic corridor between China, Russia and Mongolia, as well as for the "New Silk Road" route that will be laid across the province of Heilongjiang.
The goal is to unite the railway network in Northeast China with Russia's famous Trans-Siberian Railway to form a new single international railway route.
Despite being twice as large as India, Russia's Far East has a population of less than seven million people. By contrast, neighboring Heilongjiang Province has a population of over 38 million, despite being smaller than Spain.
