Oak Harbor, Washington, United States

🇺🇸 Oak Harbor is a city located on Whidbey Island in Island County, Washington, United States. Oak Harbor was incorporated on May 14, 1915.

History The Lower Skagit people have inhabited Oak Harbor (təqucid) and the nearby Crescent Harbor (č̓itusəb) since time immemorial. There were several villages in the vicinity, and the modern settlement of Oak Harbor was built over one such village.

In the early 1850s, two settlers staked claims where the city now stands—Zakarias Martin Toftezen, a shoemaker from Norway; C.W. Sumner from New England. Irish and Dutch immigrants also arrived and settled in the area. Oak Harbor was named for the area's Garry Oak trees and was incorporated in 1915 with a population of 401. Houses and businesses sprouted up along the shores of Oak Harbor as the pioneers relied entirely on water transportation until the 1900s. For the next 30 years, steamers and freighters carried passengers and freight from the Island to the mainland and back as well as Fidalgo Island to the north. The city grew following the completion of Deception Pass Bridge on July 31, 1935, and Naval Air Station Whidbey Island on September 21, 1942. The bridge, which linked Whidbey Island to Fidalgo Island and the mainland, was a Public Works Administration project built by the Civilian Conservation Corps. A nearby state park with 4,100 acres (17 km²) of forest, campsites, and trails was also developed.
