ShopRite in West Haven is closing at the end of July.
The market at 1131 Campbell Ave. will close on July 29 and 148 employees will be affected, according to the notice given to the Connecticut Department of Labor.
"The closure has been prompted by the company's decision to discontinue the operation of business at that location," a letter ShopRite sent to the Department of Labor says.
West Haven Mayor Ed O'Brien said he was surprised by the announcement, but pointed out that a ShopRite recently opened three miles away in Orange.
In a statement, a company spokeswoman said the lease on the site was nearing the end of its term and the decision was made based on rising costs.
"All the associates from the West Haven location are welcome to apply for jobs at our other store locations in the area, and many have already done that," Karen O'Shea said. "We are hoping to place between 80 and 100 of those associates in new positions at our other stores."
Mayor O'Brien said work is underway to bring a new grocery store to the area.
