Charleston International Airport will soon begin adding more parking for the growing number of passengers it serves.

Work should begin by late March or early April on the addition of 428 new parking spaces in a wooded area adjacent to the existing surface lot behind the parking deck.

Construction will take a little over five months on the $1.4 million project awarded to Sanders Brothers Construction Co. of North Charleston, according to airport spokeswoman Becky Beaman.

The airport saw a record 2.5 million passengers pass through its terminals in 2011, 25 percent more than the previous year. The number of passengers is expected to double by 2030.
