The US Federal Aviation Administration has broken ground on a $69m air traffic control tower and terminal radar approach control facility at Cleveland Hopkins International Airport in Ohio, US.
The new 324ft-tall tower will replace the existing one, which has been operating since 1988.
The facility will have a tower cab with eight air traffic positions where controllers direct aircraft in and around the airport and a radar facility that controls air traffic within a 30-mile area around the Cleveland metropolitan region.
The tower will be equipped to give air traffic controllers more precise, system-wide information about weather and flight data.
Construction will be completed in 2014.
