Gig Harbor is the name of both a bay on Puget Sound and a city on its shore in Pierce County, Washington, United States. The population was 6,465 at the 2000 census. Gig Harbor is known as the gateway to the Olympic Peninsula. Due to its close access to several state and city parks, and historic waterfront that includes boutiques and fine dining, it has become a popular tourist destination. Gig Harbor is located along State Route 16, about six miles (10 km) from its origin at Interstate 5, over the Tacoma Narrows Bridge. A 1.2 billion dollar project to add a second span to the bridge was recently completed. During off-peak traffic times, Tacoma can be reached in 20 minutes and Seattle in less than an hour. Based on per capita income, Gig Harbor ranks 49th of 522 areas in the state of Washington to be ranked.
