Experts say 1/3 of Americans will be traveling tomorrow, Wednesday and again on Sunday for the holiday.

Just in time for some of the busiest travel times of the year, Charleston International Airport has begun remodeling and construction.

It's a $189M improvement project destined to transform the airport to a bigger, better, and much more appealing environment.

"Some of the major features of the project: we're constructing and consolidating TSA screening areas, a new rental car pavilion on the west end, adding a third baggage carousel, expanding from ten to fifteen gates as well as renovating the entire interior of the terminal so we're very excited to have this project underway," Deputy Director of Planning, John Connell said.

While the majority of the construction is only happening outside right now, it will move to the interior of the building in January so the airport is asking for your patience in advance.

Most would think this is terrible timing. AAA Carolinas predicts hundreds of thousands of people in South Carolina will travel this week. However, the airport insists Charleston should have a smooth takeoff.

"We don't expect it to cause traffic, it is a heavy week for us at the terminal. We do recommend plenty of time to get to the airport, park your car, check in with respective airline, get through TSA screening process," Connell said.

The airport said they typically see 15,000 passengers come through over the Thanksgiving holiday. So, arrive a couple of hours in advance to avoid the rush.

Those crowds also mean parking lots will fill up. The airport said they will open overflow lots (remote parking) with free shuttles in the event that the garage and surface parking are full.

Late Monday officials informed News 2 that workers had hit a water line during the construction.  Officials issued a Boil Water Advisory.  Passengers may notice that drinking fountains will not be turned on.  The airport plans to shut the water off after the last plane lands Monday.  They plan to make repairs and have the water running by 5 a.m. Tuesday.
