Work was completed on the first-ever railroad bridge connecting Russia to China in early April, as Russian engineers installed the final steel beam in its section of the structure over the river called the Amur in Russian and the Heilongjiang. China finished its part of the work last October, as the structure successfully spanned the world's 10th longest river, which markets the boundary between the two countries. Officials say the bridge will open for public use after the necessary inspections in July this year.
