From Wikipedia, the free encyclopedia.
Bainbridge Island is an island in Puget Sound. Part of Kitsap County, Washington, it lies due west of the city of Seattle. On the Kitsap Peninsula, Bremerton and Poulsbo lie across the Port Orchard channel to the west, and the city of Port Orchard lies across Rich Passage to the south.
The city of Bainbridge Island has occupied the entire island since February 28, 1991, when the former City of Winslow (around 1.5 square miles of land on Eagle Harbor, incorporated August 23, 1947) annexed the rest of the island.
The island is just under 28 square miles in area, with a population of 20,750 as of 2001.
Bainbridge Island is connected to the Kitsap Peninsula by a bridge carrying WA-305 over Agate Pass, and to Colman Dock in Downtown Seattle by Washington State Ferries service from Winslow.
