Gatwick airport has secured £10 million of government funding for the redevelopment of the transport hub.
Gatwick said the £120.5 million redesign will transform the station and passenger experience, with work scheduled to start in 2017 and complete in 2020.
The announcement today by the Department for Communities and Local Government minister was funding that the Coast to Capital Local Enterprise Partnership (LEP) will put toward the station’s redevelopment.
Gatwick will also contribute £30 million, Network Rail £30 million, with government contributing the rest.
Improvements to the new station include the doubling in size of the concourse area, more escalators and lifts to improve access to all platforms and “Intuitive passenger flow and clear concise information”.
Gatwick said the changes will help manage the expected growth in air passengers using the single runway airport, with demand at the station set to increase five million to 20 million rail passengers a year by 2025.
Guy Stephenson, Gatwick's chief commercial officer, said: "Gatwick has transformed itself in recent years and millions more passengers are benefiting from the world class service the airport now offers.
“The redeveloped station will complement Gatwick’s transformation and our passengers will experience a seamless transition between the airport and the new station.
“The whole project is a fantastic example of the public and private sector working together to deliver a world class transport hub. It’s not just our air passengers that will benefit from the transformation, over 1 million other business travelers using Gatwick station every year."
