It had seven spans of 66.22 m and two spans of 15.24 m. In 1908 the second railway bridge was built downstream of the older one. The spacing of supports and spans were the same as in the older bridge. During World War I, both bridges were blown up and then rebuilt, first temporarily and then permanently. Again both were blown up in 1944. In 1945, a temporary crossing was built. In 1947 a permanent bridge was rebuilt, partially replacing rivets with welding. On the pillars of the older bridge, the GdaƄski Bridge was built (not in this study). In 1963 welded connections were strengthened, in 1980 the structure of the northern track was replaced. In 2016, the northern track was renovated. The replacement of the structure of the southern track is ongoing since 2018.}, type={Article}, title={The history of the railway bridges by the Citadel in Warsaw}, URL={http://ochroma.man.poznan.pl/Content/115655/PDF/11_ace-2019-0011.pdf}, keywords={bridges, Citadel, destruction, history, reconstruction, steel, truss, Warsaw}, }
