As for the essence of design solutions for reconstruction work, the following
should be noted. Depending on the variants considered for destruction of bridge
structures, technical recommendations were formulated for renovation work on each
variant separately, based on the results of calculations and developed basic design
solutions for superstructure and supports of the Paton Bridge. In particular, for all
four variants considered for the bridge structures’ destruction, superstructures which
have collapsed or have permanent deformations of such magnitude that make them
unsuitable for further operation are supposed to be replaced with new structures
