Special cancellations from October 18 to December 17, 1988 Ship lifts, lifting and drawbridges Waterways have always played a major role in the history of transport. The need for effective use on the one hand and the production of secure land connections on the other hand has led to imposing structures. Their most important ones are preserved as technical monuments. Special technical solutions, building construction and architecture as well as their landscape character characterize these monuments of the traffic history. 70 Pfennig value: drawbridge with lock in Altfriesack (district Potsdam) As one of the few surviving bridges of this construction, it spans the Ruppiner Wasserstraße at the river kilometer 29,163.
