The runway at Gibraltar's airport is famous for crossing the main road between Gibraltar and Spain!
Several times a day, when a plane is due to land or take off, sirens sound and the road closes. First, pedestrians that are crossing the road are hurried up and barriers prevent any further people from walking across the road. Then, a few minutes later, the barriers come down to prevent traffic from driving along the road.
Shortly after the plane has landed or taken off, the barriers go up again and normal commuter business is resumed!
This short video was filmed as we were standing at the barrier waiting for a small aircraft to take off.
As airport runways go, Gibraltar's is surely one of the most spectacular in the world!
