As the traditional center of shipping and port activities in the Hampton Roads region, Norfolk, Virginia's downtown waterfront historically played host to numerous and often noxious port and shipping-related uses. With the advent of containerized shipping in the mid-19th century, the shipping uses located on Norfolk's downtown waterfront became obsolete as larger and more modern port facilities opened elsewhere in the region. The vacant piers and cargo warehouses eventually became a blight on downtown and Norfolk's fortunes as a whole. But in the second half of the century, Norfolk had a vibrant retail community in its suburbs; companies like Smith & Welton, High's, Colonial Stores, Hofheimer's, Giant Open Air, Dollar Tree and K & K Toys were regional leaders in their respective fields.
