The port bridge in Nowa Sól is the only movable bridge in Poland with a lifting span. It is one of the most valuable technical monuments not only in the country, representing the type of bridge construction and technical thought of the first half of the 20th century.
The bridge was made by a company from Wrocław - Dittmar Wolfsohn & Co., in cooperation with the company August Klönne from Dortmund and put into operation in 1927. Located on the port canal, in place of older wooden bridges, the first mention of which comes from 1743. The bridge was damaged in 1945 by German troops, renovated in 1954-1956. Then the manual drive system was replaced with an electric one. Another comprehensive renovation was carried out in 1990-1992. While maintaining the original, general structural layout, new solutions were introduced that partially changed the silhouette of the facility - the bridge was widened and raised. The bridge is located over the port canal, along Al. Wolności, in the southwestern part of the city. Made of a single-span steel structure, with a 6 m wide road and adjacent sidewalks slightly over 1 m wide, covered with bituminous mass, placed on reinforced concrete abutments. Lever lifting mechanism based on steel ropes wound or unwound on electric or manual drums and counterweights of concrete and steel blocks. The lifting mechanism is located in the engine room, accessed via a steel ladder from the maintenance platform.
The facility is available.
