Is it possible to drive into Gibraltar Airport's runway?
There are no physical restraints to entering the runway when the road is open.

You can see from this video of the crossing that Gibraltar police and the base for the Royal Air Force are present. The runway is owned by the Ministry of Defence. Anyone attempting to drive on the runway will probably be intercepted in seconds, although I am not aware of any reported attempts.

They also have a street sweeper to take care of FOD (foreign object debris).1



There are plans to build a new four-lane diversion road and tunnel section. Construction started in 2008 but it still hasn't been completed as of 2018. The crossing across the runway will be kept for exceptional, specific, or emergency use but pedestrians will still be able to use the crossing.
