An authen­tic Roman bridge built in 65 BC. The bridge was used for its intend­ed pur­pose until the mid­dle of the 20th cen­tu­ry, but was flood­ed dur­ing the con­struc­tion of a pow­er plant on the Kura Riv­er. Now the bridge is com­plete­ly under water. If you’re lucky, you might see it when the pow­er plant low­ers the water lev­el.
