Raleigh-Durham International Airport (RDU) in the US is planning to renovate its ageing Terminal 1 at a cost of $60m.
The upgrade will include consolidating the multiple ticket lobbies, bag claims and passenger security screening checkpoints.
The project will also involve consolidating the operations of Southwest, JetBlue and Airtran into the main section of Terminal 1 and simplifying the airline check-in and security screening process.
The airport will also develop a pre-security concessions area and reconfigure the security screening checkpoint as part of the upgrade.
The RDU Airport Authority's Capital Projects Team said construction on the terminal will begin in early 2012 and will be complete in about 18 months.
RDU has already spent nearly $570m to build Terminal 2, which has 32 gates and handles most of the airlines that fly into the airport.
