The Queen Emma Bridge is a floating pontoon bridge that connects Punda and Otrobanda across the Sint Annabaai. When a ship needs to pass through the harbour — which happens several times a day — the bridge swings open on its hinge, pivoting out of the way like a giant door, and a free ferry takes pedestrians across instead. Watching the operation is unexpectedly satisfying.
The bridge is pedestrian-only and takes about three minutes to cross. The views from the middle, with the Handelskade facades to one side and the open Caribbean on the other, are excellent. Cross it at least once in each direction.
