Airport Loop is the designation for the portions of state highways that form a circumferential highway around Baltimore/Washington International Thurgood Marshall Airport (BWI Airport) in Anne Arundel County in the U.S. state of Maryland. The loop runs through the communities of Linthicum, Ferndale, and Hanover. Airport Loop consists of a section of Maryland Route 170 (MD 170) along the western and northern sides of the loop; the entire length of MD 162 on the eastern side of the loop; and a segment of MD 176 on the southern side of the loop. Airport Loop intersects Interstate 195, which provides freeway access to the airport terminal, and is connected to I-695, I-97, and MD 100 via connecting highways. The MD 170 and MD 162 sections of Airport Loop are part of the National Highway System.〔 ==Route description== Airport Loop begins at I-195 (Metropolitan Boulevard) signed as part of MD 170 (Aviation Boulevard). Airport Loop meets the Interstate highway at a partial cloverleaf interchange at the northwest corner of the loop. I-195 heads south to the airport terminal and north toward MD 295 (Baltimore–Washington Parkway) and I-95, which connect BWI Airport with Baltimore and Washington. Airport Loop passes under the BWI Trail and heads east as a four-lane divided highway. At the next intersection, the loop meets Elm Road, which heads south toward the airport terminal and hourly, daily, and express parking lots, and north toward Elkridge Landing Road, which passes through the BWI Hotel District and leads to off-site parking. Immediately east of the intersection, Airport Loop crosses at-grade the Baltimore Light Rail. The loop passes to the south of the BWI Business District station, whose kiss and ride and park and ride facilities can be accessed via Elkridge Landing Road at the next intersection. The air cargo facility is also accessed from that intersection. Airport Loop continues east, paralleling the light rail until the first route change occurs where MD 170 leaves the loop to the north as Camp Meade Road toward I-695 and the loop continues east as MD 162 (Aviation Boulevard).〔〔 Airport Loop passes the entrance to both long-term parking lots before intersecting Andover Road, which is unsigned MD 762 and connects with MD 170 in Linthicum. At this point, the loop turns south and is flanked by residential subdivisions to the east and the BWI Trail on the west. The next intersection features Ferndale Road heading east and the entrance to BWI Airport's general aviation facility. Airport Loop passes the offices of the Maryland Aviation Administration before reaching Cromwell Drive, which serves an industrial park and leads to ramps to and from southbound I-97. Airport Loop continues south to an intersection with MD 176 (Dorsey Road) and Stewart Avenue. MD 176 east leads to an interchange with access to northbound I-97. Airport Loop turns west onto westbound MD 176.〔〔 Airport Loop heads west as a four-lane divided highway that reduces to a four-lane undivided highway with intermittent center turn lane as the highway passes the aircraft observation park, where the BWI Trail again parallels the loop. The loop passes the overflow parking facility on the north as it passes an industrial park on the south before reaching MD 652 (Old Telegraph Road). A long ramp for northbound MD 170, designated MD 170A, exits westbound MD 176 before MD 176 intersects MD 170, which heads south as Telegraph Road toward an interchange with MD 100 and north as Aviation Boulevard. Airport Loop turns north onto MD 170.〔〔 Airport Loop heads north as a four-lane undivided highway paralleled by the BWI Trail on the east and the Amtrak Northeast Corridor to the west through the trees. The loop intersects Stoney Run Road, which provides access to multiple rental car facilities and a business park. Stoney Run Road heads east then loops around to cross over Airport Loop; this is where the BWI Trail switches to the west side of the highway. At the intersection with Amtrak Way, which is unsigned MD 995 and leads to the BWI Rail Station, the BWI Trail splits to the north to follow Amtrak Way as Airport Loop curves to the northeast. Airport Loop completes its circuit of BWI Airport at the interchange with I-195.〔〔 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「Airport Loop」の詳細全文を読む スポンサード リンク
