Two of the four Borders bookstores in Louisville will close as part of the company's Chapter 11 filing.Borders is closing about 200 stores, among them the 4th Street and Hurstbourne Parkway locations.Mayor's spokesperson Chris Poynter says the city must now work on filling the soon-to-be empty retail spaces, particularly the one on 4th Street, which anchors 4th Street Live."It's unfortunate that we're losing an anchor tenant, but businesses have come and gone all the time at 4th Street Live, so we're pretty confident the Cordish Company with their national experience and their retail experience can find a viable use for that space if indeed the Borders closes," he says. "The mayor will be meeting with the Cordish Company next week—a meeting he'd had planned for a while—and the Borders closing will be among the things they discuss."The Cordish Company handles the 4th Street lease for Borders. Poynter says he's confident the company will find a new retailer to fill the space, though it's too early to say when that may happen.The other two Borders stores in Louisville—on Bardstown Road and Shelbyville Road—will tentatively remain open.To see the full list of stores that will be closed, click here.
