The 2.6 million passengers traveling through Charleston International Airport will encounter a lot of construction work over the next two years as the aging terminal undergoes a total makeover.

To help them navigate their way through work zones and update them on areas of redevelopment, Charleston County Aviation Authority on Thursday unveiled a new website, www.chs-trip.com.

The site offers an overview of the construction plan, a time line, before-and-after photos, work alerts, contact information and a video featuring Aviation Authority Chairman Andy Savage and Fentress Architect’s Tom Theobald talking about the $189 million project. Fentress is designing the 28-year-old terminal’s overhaul.

“We’re excited to provide the community, our passengers, airport employees and our tenants with a way to follow the construction progress through engaging and informative visual content and through stories about the work and the people behind the work,” said Hernan Pena, chairman of the Aviation Authority’s Terminal Redevelopment and Improvement Plan committee.

In addition, passengers will soon see signs around the terminal with a QR code symbol that will enable mobile devices to take them directly to the website.

“Things could get a little loud and a little messy, but the temporary inconvenience will lead to long-term improvement of the customer experience at Charleston International Airport,” Airports Director Paul Campbell said. “We’re going to do our best to keep people informed, keep people safe and make it as easy as possible to navigate around the construction.”

Terminal redevelopment includes adding six new gates, a third baggage carousel, new rental car pavilion, consolidated security checkpoints, a dome over the atrium and numerous other structural and cosmetic changes.

Work is expected to be completed in August 2015.
