Due to mismanagement at the hands of Soviet authorities, one of the main aerial trams experienced a major malfunction, causing the 1990 Tbilisi aerial tramway accident and remaining closed ever since. Since October 2017, the aerial tram has been under reconstruction, keeping the old culturally significant lower station but with plans for new gondolas, masts, upper station and other infrastructure. The project is carried out by Doppelmayr Garaventa Group.
