With seawall construction and site work, the long journey of eight years and five months had started. The first phase construction was substantial in scale with all of Korea's advanced construction methods put together for use. With completion of Terminal 1, Runways 1 and 2, aprons, and various ancillary facilities, Incheon Airport took its first step toward becoming a global airport that can compete with top airports around the world.

Through the second phase construction, further expansion was made with construction of concourses, runway 3, cargo terminals, and surrounding facilities. With this, Incheon International Airport took a step forward to becoming a high-tech airport with world-class infrastructure and a hub airport that represents Northeast Asia.

Korea took another leap forward entering the era of multiple international flight terminals. Incheon International Airport leapt to become a leading global airport setting new standards and through the three phases of construction became capable of handling 77 mil. passengers and 0.5 mil. tons of cargo annually, which firmly established a stepping stone to becoming a global mega-hub airport.
