Stop & Shop Supermarket Co. planned to open its first converted A&P locations on Long Island Friday and begin conversions on a second wave of stores.

Stop & Shop will convert a total of 25 grocery stores it acquired from the Great Atlantic & Pacific Tea Co., including nine locations on Long Island. It is closing the stores for about a week before reopening under the Stop & Shop banner.

Stores expected to open Friday include the Waldbaum's stores in East Hampton and Southampton, along with locations in the Bronx, Ozone Park, Queens, and Brooklyn.

The second wave of Stop & Shop grand openings is planned for Oct. 23 and includes the Pathmark in Greenvale, along with locations in the Bronx, Springfield Gardens and Howard Beach in Queens, and South Orange, New Jersey.

"Our store conversion team is doing a great job, and we can't wait to open the first wave of stores to our customers," Don Sussman, president of Stop & Shop New York Metro Division, said in a statement.

During the process, groups of up to five stores will close for about 7 days, but pharmacies and banks within the locations will remain open. The stores will reopen as Stop & Shops and have new decor, refrigeration systems and lighting, as well as other improvements. Modifications at all of the stores are expected to be completed by Nov. 13.

Aside from the stores in Greenvale and the Hamptons, the other Long Island stores bought by Stop & Shop include Waldbaum's locations in Baldwin, Hicksville Road in Massapequa, Long Beach and Huntington; and Pathmarks in Seaford and Franklin Square.

Stop & Shop has hired about 1,100 former Pathmark and Waldbaum's workers at the nine Long Island stores it acquired from A&P, which is in Chapter 11 bankruptcy.
