Gibraltar Airport (which is not part of Spain as a lot of readers pointed out) is a very unusual airport. To my knowledge, it is the only one where the runway actually intersects with a major highway. When a plane has to take off or land, traffic is shut down. The History Channel program Most Extreme Airports ranks it as the fifth most dangerous airport in the world and the most dangerous in Europe. We have heard of highways being used as runways in some countries. But this is the first time I have seen roads crossing a runway and road traffic being stopped by a traffic light while an aircraft takes off or lands! Absolutely amazing! British Gibraltar has very little area, and the important airport runway takes up a major portion of land. To drive from Gibraltar to Spain, vehicles must cross the runway. Check out this amazing airport. Enjoy.
