DANVILLE — Another Weis Markets store is expanding in The Valley.  Work has already begun on the expansion and upgrade of the Danville store on Continental   Boulevard.  The project includes a 3,200 square-foot expansion, a new exterior, all new decor, a new pharmacy and many new departments.  The project is expected to take a year.  In the last several years, both the Lewisburg and one Sunbury Weis Markets have been expanded.  A plan is also in the works to expand the Weis store along Route 522 in Selinsgrove.
