Interstate 205 (I-205) is a loop route that serves the Portland—Vancouver metropolitan area in the U.S. states of Oregon and Washington. I-205 is officially named the War Veterans Memorial Freeway in both states, and is known as the East Portland Freeway No. 64 in Oregon (see Oregon highways and routes). I-205 passes east of downtown Portland and Vancouver, thus serving as a bypass route of I-5, which runs directly through the downtown areas of both cities. The northern terminus of the highway is located north of Vancouver in the suburb of Salmon Creek, and the southern terminus is in the Portland suburb of Tualatin. ==Route description== I-205 starts in Tualatin, Oregon, at a semi-directional T interchange with I-5. From I-5, the highway heads east towards the towns of West Linn and Oregon City where it crosses the Willamette River between interchanges for Oregon Route 43 (OR 43) and OR 99E. In West Linn, there is a view point exit for the northbound lanes, providing a scenic overlook of Willamette Falls. In Oregon City, the highway curves northward, crossing the Clackamas River concurrent with OR 213 and entering the town of Gladstone. OR 213 splits from I-205 again at exit 13 in Clackamas, and the next exit north on I-205 provides access to Sunnyside Road and Clackamas Town Center. North of Clackamas, the freeway crosses the Portland city limits, passing through the eastern portion of the city, where it intersects I-84 and U.S. Route 26 (US 26). On the northern side of the city, just before crossing the Columbia River on the Glenn Jackson Bridge, I-205 has an exit for Airport Way, which provides access to Portland International Airport. On the Washington side of the river, I-205 serves the eastern parts of the city of Vancouver, and has interchanges with two freeways, State Route 14 (SR 14) just north of the Columbia, and SR 500 near Vancouver Mall.〔 From the SR 500 interchange, I-205 curves northwest back towards I-5, where it ends in the town of Salmon Creek. This interchange with I-5 is not complete, as there is no direct access from I-5 northbound to I-205 southbound, or from I-205 northbound to I-5 southbound. These missing movements are completed via Northeast 134th Street, one exit to the south. A bicycle and pedestrian trail follows I-205 for much of its distance in the Portland metropolitan area, and connects to the Springwater Corridor trail near the Foster Road exit. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Interstate 205 (Oregon–Washington)」の詳細全文を読む スポンサード リンク
