The wall will remain for two years as construction begins on the $2.5 billion "Transform RDU" project, aimed at increasing capacity and reducing wait times.
According to RDU official Kerry McComber, the construction will not impact travel plans, as all security lanes and ticketing areas will stay open to ensure travelers can reach their destinations quickly and safely.
Passenger Nicolas Kressman recalls when RDU had only one terminal.
"It's exciting to see it grow and be able to go to more places and have more accommodation," he said.
Planned improvements include a new runway, expanded terminal and parking, and enhanced roadways.
The expansion follows record-breaking passenger traffic, prompting the airport to ensure its facilities can support growth and improve the passenger experience.
"We've seen lots of new flights and destinations ... and so that's why we are embarking on this project and others," McComber said, "so that we can accommodate more growth in the future as well as improve the passenger experience for everybody."
The project aligns with long-term plans to support future growth and enhance the passenger experience.
