Feasibility studies to evaluate idea of Thames Gateway airport in estuary off Kent's Isle of Sheppey

The mayor of London has proposed plans for an island airport in the Thames Estuary to replace Heathrow airport.

City Hall officials are examining plans for a 24-hour airport off the Isle of Sheppey in Kent, and have reportedly hired an engineering consultant to prepare a feasibility study.

The Thames Gateway airport, already dubbed Boris Island, would have two runways and could be an alternative to further expansion at Heathrow airport. One report even suggested that Heathrow could be closed after construction of the new airport.

Government plans for a third runway at Heathrow have fallen foul of the Conservatives and UK environmental campaigners, not to mention the mayor of London.

A spokesperson for the mayor told the Sunday Times that Johnson “wants to undertake a study to establish the feasibility of the idea once and for all and is in the process of examining the best way to take the study forward”.
