Stop & Shop Supermarket Co. Thursday announced its fourth wave of store openings as it converts 25 grocery stores it acquired from the Great Atlantic & Pacific Tea Co., including nine Long Island stores.

The latest openings, planned for Nov. 6, will include Waldbaum's locations in Baldwin and on Hicksville Road in Massapequa, and a Pathmark in Seaford. Other locations to be converted are in Bayside, Queens, and Closter, New Jersey. The stores closed Thursday for renovations.

With each wave, Stop & Shop closes former A&P-owned stores for about a week before reopening them under the Stop & Shop banner. During the conversion, pharmacies and banks within the locations remain open. Modifications at all of the stores are expected to be completed by Nov. 13.
