Delaware's only Costco Wholesale, near Christiana Mall, is expanding

Wholesale shoppers soon will be able to fill up their gas tank when they visit Costco's Christiana location.

Construction began recently on a Costco gas station to the right of the existing entrance. The plan, approved in July by New Castle County, also calls for a nearly 2,000-square-foot expansion close to the liquor store.

Costco representatives declined to offer a timetable for the gas station's construction or further details regarding the expansion.

"Unfortunately, it is our company policy to not comment regarding future Costco warehouses or building updates until we are ready to share details about the new location or building updates," a representative said.

Located just outside the Christiana Mall, the first and currently the only Costco in Delaware opened in 1998. The next closest location is in Glen Mills, Pennsylvania.

The gas station, like the warehouse store, will only be accessible to paying Costco members.

The company boasts that its gas stations offer the highest quality gas and are more efficient than a typical gas station. The stations are only accessible from one direction and have extra long hoses that can stretch to either side of your car.

Once constructed it will be the only gas station adjacent the Christiana Mall and the Christiana Fashion Center.
