New Lisbon Airport (Portuguese: Novo Aeroporto de Lisboa, NAL) is the currently planned site for construction of a new Lisbon Airport, scheduled to replace or complement the current Portela Airport in the year 2017.
As of February 2008, the location was subject to public consultation. After years of debating whether Rio Frio or Ota would be the place to build the new Lisbon airport, a new location was proposed in Alcochete and won as it was more accessible due to the good infrastructure nearby, such as the Vasco da Gama Bridge.
The location of Alcochete as the construction site of the future Lisbon Airport was confirmed by the Portuguese Government on 8 May 2008. The estimated cost for the project is €3 billion (approximately $4,5 billion). It was intended to start construction late 2010 or early 2011. In May 2010, forced by the financial crisis, Prime Minister José Sócrates put the project on halt.
