Are bridges in Uzbekistan earthquake resistant?
There are currently 14,331 bridges in Uzbekistan, with 7,628 located on highways and 6,703 in cities, villages, and internal industrial roads, according to Ne'matulla Nishonov, the laboratory head of the Mechanics and Seismic Resistance Institute named after M.T. Orozboev at the Uzbekistan Academy of Sciences.
Most bridges are constructed with precast reinforced concrete elements and are assembled on-site. In recent years, Uzbekistan has adopted monolithic construction technology for bridges and overpasses. This technology provides a higher level of seismic resistance, and the bridge structure can withstand earthquakes with special shock-absorbing systems.
Some examples of such modern bridges include the longest bridge in Tashkent, which is 788 meters long, and the newly built bridges in Samarqand city, designed to reduce traffic congestion. As part of the government's development strategy, 1,512 bridges and other artificial structures will be slated for modernization and reconstruction in the next four years. Most bridges in Uzbekistan were built in the 1970s and 1980s, and many of them require reconstruction due to design errors and the extension of the bridges without proper modification.
