Revitalization of historic railway bridges on the example of a structure in Łęknica (Poland)

Abstract

In the article, an attempt is made to describe the scale of the problem of the revitalization of railway bridges found on lines no longer in use. The issue of changes in use of historic railway bridges is considered on the example of a bridge in Łęknica built in the years 1897-1898. The described bridge is untypical due to the inverted parabolic truss girders and the placement of 9 spans in a horizontal arch of a small radius. The structural solutions of the railway structure as well as the scope of construction works carried out in an effort to adapt it for pedestrian and cyclist traffic have been presented.
