Gig Harbor is one of several cities and towns that claim to be "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 6 mi (10 km) from its origin at Interstate 5, over the Tacoma Narrows Bridge. A $1. 2 billion project to add a second span to the bridge was completed in 2007. From Gig Harbor, Tacoma can be reached in just under 20 minutes and Seattle in just under an hour.
