North Terminal has 31 gates with jetbridges including three which can support an Airbus A380. Construction began on the North Terminal on land previously earmarked for a second runway in the draft plan of May 1970. This was the largest construction project south of London in the 1980s, costing £ 200 million. In 1991 a second aircraft pier was added to the North Terminal. On 16 May 2005, the new Pier 6 opened at £ 110 million, adding 11 pier-served aircraft stands. The pier is linked to the North Terminal's main building by the second-largest air passenger bridge in the world,[nb 9] spanning a taxiway and providing passengers with views of the airport and taxiing aircraft.
A large extension to the terminal was opened by former Prime Minister John Major in November 2011.
