Railway swing bridge in Gdańsk, Dismantled railway bridge site in Stogi, Gdańsk, Poland

The railway swing bridge in Gdańsk was a single-track, three-span steel bridge over the Martwa Wisła between Stogi and Rudniki, parallel to the Jan Paweł II suspension bridge. The two outer spans were truss structures, while the middle span was a plate-girder swing span resting on three concrete piers and abutments; the largest central pier served as its axis of rotation. The swing span had been immobilized since the 1960s, and the bridge was dismantled in 2016.

Built in the early 1900s, this bridge was created to expand the rail network and handle growing transportation needs. It represented an early engineering solution to combine rail and ship traffic in one location.

The bridge carried line 226, the only rail link between the Northern Port and the eastern harbour and the rest of Poland. Freight trains, mostly coal wagons and container cars for the Gdańsk Container Terminal, were its only users. In early 2015 city councillors proposed converting it into a pedestrian and cycle path, but a technical study rejected the idea and the bridge was dismantled in 2016.

The bridge no longer exists: it was dismantled in 2016, and its supports were removed from the riverbed that September. The new double-track railway bridge stands in its place, parallel to the Jan Paweł II suspension bridge on the Sucharski route. Look for the site between Stogi and Rudniki, near the container terminal.

The rotating span was already immobilized from the 1960s, so for its last decades the bridge never actually swung open. Water traffic still passed beneath that middle span, guided by markings on the structure. The middle span was a plate-girder section, while the two outer spans were trusses.
