Gig Harbor was officially incorporated on July 12, 1946. Commercial fishing, boat building, and logging dominated the economy until the construction of the first Tacoma Narrows Bridge in 1940. Until then, the primary method of transportation between Gig Harbor and the economic center of nearby Tacoma was by steamship. Starting in 1836, steamships started plying the waters of Puget Sound and quickly developed into what was eventually dubbed the "Mosquito Fleet". Gig Harbor, isolated from Tacoma and Seattle by Puget Sound and the Tacoma Narrows, could not be reached by automobile or horseback except by a very long and arduous trip south around Puget Sound and Hammersly Inlet. The boom was to be short lived, as the first bridge collapsed just months after it was completed. The resource demands of World War II prevented another bridge from being built until 1950. Between the time when the first bridge collapsed and when the second bridge was completed, a state-run ferry service delivered drivers directly into downtown Gig Harbor. Remains of the ferry dock can still be seen just outside the mouth of the harbor at the southeast end of Harborview Drive. The area has been turned into a small park, where the public can see a panoramic view of the Cascade Mountains, Point Defiance, and Mount Rainier.
