Longs Drug Stores plans a second new store in Hawaii featuring a drive-through pharmacy.

The store is slated to be built near the entrance of Mililani Mauka on a 1.9-acre site next to a McDonald’s restaurant and a Tesoro gas station and convenience store.

CVS Caremark Corp., which owns Longs, bought the parcel from Mililani’s master developer Castle & Cooke Hawai’i.

Castle & Cooke said it has an option to construct five additional retail buildings that would expand the tenant mix on the site at the corner of Meheula Parkway and Ainamakua Drive.

The Longs store is designed to be 23,000 square feet and include a two-lane drive-through for pharmacy orders. The store is expected to open in the first half of 2012, and would be one of 46 Longs stores in Hawaii and 29 on Oahu. The first full-size Longs store with a drive-through is scheduled to open July 19 in Pearl City.
