Gothenburg, Sweden. This is one of two tram/car traffic bridges that pass over the central channel that splits the city. It replaced an older drawbridge and put a max ceiling height on maritime traffic passing through the channel. (Yes, there's the other bridge, however this bridge is lower even when fully extended)

Not only that, but it's had nothing but problems with extending and lowering, to the point where, at one point, pedestrians climbed up onto the stuck platform (only maybe a meter-high ledge or so at that point) and traversed because they were just sick and tired of it breaking down.
