Hayden Island

Portland's Island Community

Hayden Island is an island in the Columbia River between Vancouver, Washington and Portland, Oregon. The wide main channel of the Columbia (and the Washington/Oregon state line) passes north of the island. To the south, sheltered by the island, is a smaller channel known as North Portland Harbor. Much of Hayden Island (and connected Tomahawk Island to the east) is within Portland city limits, and recognized as one of its 95 neighborhoods.

Marina at Hayden Island

Interstate 5 provides the only roadway connection to the island, via the northernmost Oregon exit, to the rest of North Portland and, with the Interstate Bridge, to Vancouver to the north. The BNSF Railway crosses North Portland Harbor (via the Oregon Slough Railroad Bridge) and the western part of the island to the west of I-5, before crossing the Columbia via the Burlington Northern Railroad Bridge 9.6. The east end of the island, often called Jantzen Beach, has highly developed retail areas near the freeway, hotels, offices, manufactured home communities, and condominium complexes. Further east there are several houseboat moorages and marinas.

Until the Interstate Bridge opened in 1917 ferries provided service between Portland and Vancouver from landings on the island's north shore. After the opening of the bridge, streetcar service opened Hayden Island to amusement park developments due to its beaches and strategic location. Jantzen Beach, the last operating amusement park, closed in 1970. Tomahawk Island, just off the east tip of Hayden Island, became another amusement park—Lotus Isle—for a few years in the 1930s.

Because Oregon does not have a state sales tax, and Washington has one of the higher state sales taxes, it is common practice for people in Southwest Washington to travel to Oregon for larger taxable purchases. The Jantzen Beach Shopping Center and many hotels populate this part of the island. A narrow neck of land connects Hayden Island to Tomahawk Island (not an independent island since construction of the linkage), which has numerous marinas, yacht clubs, and the Yacht Harbor Club apartment community.
