It was built during World War II to connect the Pentagon with U.S. Route 50 (US 50) and northern Arlington to the west and Washington, DC, to the east. Its route parallels the southern boundaries of Arlington National Cemetery. At its southernmost point, Route 27 passes through a complex interchange with Interstate 395 (I-395, Shirley Highway).〔〕 called the "Mixing Bowl,"〔(【引用サイトリンク】title=Definition: mixing bowl )〕 although local motorists more recently use that term also to refer to the Springfield Interchange on the Capital Beltway in Springfield. It is an important commuter route as well as providing access to a number of military installations, the cemetery and national memorials. Because Route 27 is the closest road to the site of the September 11 attack on the Pentagon, the route has been designated the "9/11 Heroes Memorial Highway." ==Route description== Route 27 begins at an interchange with US 50. It then has an interchange with 2nd Street South, which serves as an entrance to Fort Myer. The next interchange with Route 244 offers a very short merge area because of the proximity to the exit ramps to I-395 and Arlington Ridge Road. The Mixing Bowl is the first interchange in Northern Virginia with a three level bridge—ramp from I-395 to westbound Route 27 on the lowest level, eastbound Route 27 to Mixing Bowl in the middle; and southbound I-395 on top. In 1970 this was followed by a second three level stack—Joyce Street South on the lowest level, eastbound Route 27 on the middle bridge and I-395 on the top level.〔 At this point, Route 27 becomes a part of the collector lanes and ramps of the Mixing Bowl until its second interchange with Route 244. Also, coincident with the second Route 244 interchange, Route 27 is the northern terminus of the reversible high occupancy vehicle lanes of I-395. The westbound entrance to these lanes have a series of manually closed barriers to prevent an accidental oncoming collision during the hours each day when traffic flows to the east on the HOV lanes. The final interchange in Virginia accesses Route 110, the Pentagon North Parking Lot and Boundary Channel Drive. Although the ramp from eastbound Route 27 to northbound Route 110 is open to the public, it is on the Pentagon Reservation and is patrolled by the Pentagon Police.〔〔: Operation and control of Pentagon Reservation and defense facilities in National Capital Region. Retrieved June 4, 2011.〕 The route ends at the Boundary Channel, which is the border with the District of Columbia. Route 27 is closed for large events held at the Pentagon including the annual Marine Corps Marathon and the Army Ten-Miler. A number of points of interest are visible from the highway, including (from west to east) Fort Myer (which was the site of the first military test flight),〔(【引用サイトリンク】title=Fort Myer History )〕 Henderson Hall (the headquarters of the United States Marine Corps), the United States Air Force Memorial, the Pentagon,〔 the Navy Annex, the Pentagon Memorial,〔 the Pentagon City Mall, and Arlington National Cemetery. 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「Virginia State Route 27」の詳細全文を読む スポンサード リンク
