Interstate 205 is the eastern bypass route around the Portland metropolitan area. With a modern design and additional travel lanes, regional traffic headed north to Seattle or south to Salem generally uses I-205 in lieu of I-5. Southbound Interstate 205 begins in Salmon Creek, Washington, where it splits from Interstate 5. From there it travels through Vancouver and crosses the Columbia River into Oregon. Known as the East Portland Freeway in Oregon, it heads through the eastern neighborhoods of Portland in Multnomah County.
Crossing into Clackamas County near Exit 16, Interstate 205 services the Portland suburbs of Clackamas, Gladstone, Oregon City, and West Linn. It reaches its southern terminus at Tualatin, rejoining Interstate 5.
