300 araqvinli körpüsü, Reinforced concrete bridge in Tbilisi, Georgia.

The 300 Aragvinli körpüsü is a reinforced concrete bridge spanning across the Mtkvari River and connecting different parts of Tbilisi. The structure carries both vehicle and pedestrian traffic, serving as an important link between the eastern and western sections of the city.

A single-span wooden arch bridge by engineer Gagenmeister was built here in 1851; merchant Ivan Mnatsakanov paid 25,000 rubles to free it from tolls. It decayed by 1866 and collapsed in 1869, and a ferry ran here during the 1877–1878 Russo-Turkish War. In 1882 a 95-metre metal lattice bridge on stone abutments replaced it, serving until 1952, when the Ortachala hydroelectric dam and today's reinforced concrete bridge were built (1952–1956).

The bridge's name honours the 300 Aragvians, but it was only adopted in the 1920s. Before that, the crossing was called Mnatsakanovsky after Ivan Mnatsakanov, a Tiflis resident who donated 25,000 rubles to buy the toll bridge for the city and free residents from crossing fees.

The bridge carries the road over the Ortachala hydroelectric dam, with the Metekhi bridge upstream and the Dmitry Gulia bridge downstream. On the right-bank abutment of the old 1882 metal bridge stands the Krcanisi restaurant. Cross on foot or by car; the roadway is shared with traffic.

From the bridge you can see the historic Metekhi Church and the Narikala Fortress towering above the river. This view turns the crossing into more than just a practical journey and connects visitors visually with several important landmarks of the city.
