Palm Beach International Airport in the US will build a 231ft-tall control tower near the Palm Beach Kennel Club by 2011 at a cost of $18.1m.
The new tower will include a 550ft² circular room at the top and a 9,000ft² base for administrative offices and training equipment.
Construction of the new control tower is 25% complete. The new tower will be two-and-a-half times taller than the airport's existing control tower near Southern Boulevard.
The height of the tower will enable controllers to view the airfield, clearly taking into account the airport's expansion over the next 20 years, according to a senior spokesperson from the Federal Aviation Administration.
