Federal Way, Washington

Located between Seattle and Tacoma along I-5, Federal Way takes its name from Federal Highway 99 — the old Pacific Highway. Once a quiet logging area, it boomed in the 1960s-80s with the opening of Weyerhaeuser's headquarters and the SeaTac Mall, becoming one of Washington's largest cities.
