Finally we’re seeing some real progress at Rockville’s Twinbrook Quarter commercial/residential development, future home of the much-anticipated Wegmans grocery store. Cranes have been out in full force on this stretch of Rockville Pike, where the wrecking ball soon will demolish empty buildings that once belonged to Pizza CS, Fuddruckers, Toosso, the Salvation Army Family Store and the Sheffield/Danker furniture warehouse. Sadly though, we’re still a long way off from welcoming Wegmans to Rockville — so long, in fact, that the grocery chain won’t even speculate about a potential opening date. As things stand now, a Wegmans spokesman tells us this store probably won’t even get started on construction until 2024.
