Contractors have been renovating the Russell Corp. new No. 1 mill to become the Russell Marine outdoor supercenter. Work has been underway for a year now and Russell Marine president Dave Commander said Tuesday it should open sometime in April. The 150,000 square-foot Russell Marine facility on U.S. Highway 280 will house a used boat center and a sales floor with three new product lines for Russell Marine from BassCat fishing boats, SeaArk Boats and Can-Am along with its current lines.
