Transportation

SR 20 enters Island County via the Port Townsend-Coupeville (Keystone) ferry route from the West, and departs via the Deception Pass Bridge in the North. SR 525 enters Island County from the East/South via the Mukilteo-Clinton ferry and terminates at an intersection with SR 20, South of Coupeville.

These islands are also served by a fare-free/pre-paid bus service called Island Transit.

Politics

Island County is divided in many ways between its north and south. While the north (Oak Harbor) is conservative – George W. Bush received almost 65 percent of the 2004 vote and carried all precincts – all southern and central precincts voted for John Kerry.

This is probably accounted for by the presence of Naval Air Station Whidbey Island, located north of Oak Harbor. The south-central area (Coupeville, Langley) voted over 60 percent for Kerry. Camano Island has a Republican lean and went for Bush with 52 percent of the vote in 2004, but is much less polarized than the rest of the county.
