What term describes a crossing over a waterway by a fixed or movable structure?

Explanation:
A bridge is a structure that spans a waterway to allow passage, and it can be fixed or movable. A movable bridge, like a drawbridge, is designed to open for ships, while a fixed bridge simply provides a static crossing. A tunnel crosses beneath the water rather than over it, and a marsh is a wetland, not a structure for crossing. So the term that covers both fixed and movable crossings over a waterway is bridge.
