The current bridge was designed by architect L. A. Noskov and was constructed between 1968 and 1970, developed by engineers N. P. Agapov and A. D. Guttsajt. The ‘Guttsajt’ bridge was substantially wider than its predecessor—at just under 45 metres in width—and was opened to public use on November 7 1970.
