ABSTRACT
ABSTRACT: Historical bridges are a great part of bridge population in many countries. Many of these bridges are structurally deficient and/or functionally obsolete and, therefore, require to be rehabilitated or modernized, including strengthening and change of the geometrical parameters of the structures. Criteria for classification of the historical values of the old bridges are presented and discussed based on the Polish regulations. Selection criteria of the methods for rehabilitation and modernization of the historical bridges, especially concrete ones, are presented. The relevant examples of bridge rehabilitation and modernization taken from the Polish engineering practice are given.
