All photos by Eckhard Bernstorff, please do not reuse without permission. This unassuming footbridge has a very nifty feature. It can be raised to make way for boats. The backstays are shortened using jacks, causing the towers to tilt back and the deck to arch up and out of the way. Eckhard notes: "the deck (weight 150 tons) has 14 segments. When the towers tilt back by shortening the main cables about 2.5 meters, the deck lifts 9 meters."
