Diego Aracena International Airport in Iquique, Chile, is undergoing a facilities redevelopment programme, which will make it the nation's second largest airport.
Airport owner Aerotas announced it received an investment of $12m for the facility which is expected to reopen in March.
Works include an extension of the runway and the construction of a new passenger terminal and flight tower.
The redevelopment is expected to increase passengers volumes and the number of daily flights.
A recently built cargo terminal is expected to begin operations in April 2011.
