What is a draw briidge?

A drawbridge is a type of movable bridge that can be raised or lowered to allow the passage of boats and ships while still providing a roadway for vehicles and pedestrians. It typically consists of two parts that pivot upwards or are lifted, creating a gap for vessels to pass underneath. Drawbridges are commonly found over rivers, canals, and other waterways where navigation is necessary. They are engineered to balance structural support and movement, ensuring safety and functionality.
