Philadelphia International Airport in the US will undergo a major renovation at a cost of $535m, including a $135m upgrade to commuter Terminal F.
The Terminal F upgrade will include the expansion of centre hub and passenger waiting areas, and the construction of a baggage-claim building and walkway that will connect Terminals E and F.
Other airport renovations will be seen on the runway, which will undergo refurbishment and interior signage. Additional taxiways will be constructed and old jet bridges replaced.
Another $150m will be spent on enlarging the airfield and adding gates in the international terminal, according to the Philadelphia Inquirer.
Bidding for the project will start soon and construction is expected to begin by the end of this year.
The expansion, expected to be complete in 2013, will be financed by fees charged to airlines.
