Unlike the United Kingdom and other British Overseas Territories, traffic in Gibraltar drives on the right, as it shares a land border with Spain.
[2] Older roads in Gibraltar, primarily in the city centre, are fairly narrow with a typical speed limit of 50 km/h (31 mph).
The traditional sole road into Spain, Winston Churchill Avenue, intersected with the airport's runway requiring movable barricades to close when aircraft landed or departed resulting in congestion.

In 1931 the seaplane Saro Windhover Captained by Edgar Percival for GB Airways was the first of regular passenger flights from Gibraltar to Morocco.
Scheduled civilian passenger flights are operated by EasyJet, British Airways and Royal Air Maroc.
However, GB Airways discontinued its Madrid service on 30 September 2007 and Iberia subsequently considered using smaller aircraft, possibly from its Air Nostrum regional partner – indicating that neither operator may have been able to fill their planes with passengers.
Following the takeover by EasyJet, GB Airways dropped its direct Gibraltar–London Heathrow service on 28 October 2006[19] despite apparently remaining popular.
