Maryland Route 176 (MD 176) is a state highway in the U.S. state of Maryland. Known as Dorsey Road, the highway runs from the end of state maintenance in Hanover east to MD 648 in Glen Burnie. MD 176 is a mostly four-lane highway that parallels MD 100 and forms the southern portion of the Airport Loop, a circumferential highway around Baltimore/Washington International Thurgood Marshall Airport (BWI Airport) that connects the airport with various airport-related services. The highway serves as the main connection between the Airport Loop and Interstate 97 (I-97). MD 176 was constructed in the late 1920s between Glen Burnie and Dorsey at the Anne Arundel–Howard county line. The state highway was extended west to U.S. Route 1 (US 1) near Elkridge in the late 1930s concurrent with the construction of railroad grade separations at Dorsey and Harmans. MD 176 was widened over much of its length in the late 1940s and in Anne Arundel County in the 1970s and 1980s. MD 100 became the primary highway connecting Elkridge and Glen Burnie in the mid-1990s; MD 176 was subsequently truncated at Hanover. The portion of MD 176 west of MD 295 became an eastern extension of MD 103. ==Route description== MD 176 begins at the west end of state maintenance adjacent to the cloverleaf interchange between MD 100 (Paul T. Pitcher Memorial Highway) with MD 295 (Baltimore–Washington Parkway) in Hanover. Dorsey Road continues north as a county highway through an industrial park. MD 176 heads east as a two-lane road that crosses Piney Run. The highway meets the northern edge of MD 713 (Arundel Mills Boulevard) just north of the highway's interchange with MD 100 northeast of Arundel Mills. MD 176 continues east as a four-lane undivided highway between a residential area to the south and industrial parks to the north. The highway parallels its old alignment, part of which is MD 645, through the hamlet of Harmans. There, the highway crosses over Stoney Run and the Amtrak Northeast Corridor, which also carries MARC's Penn Line. Just east of the railroad crossing, MD 176 intersects MD 170, which heads south as Telegraph Road and north as Aviation Boulevard.〔〔 MD 176 continues east along the southern portion of the Airport Loop surrounding BWI Airport on the northern edge of Severn. The highway passes between the airport property to the north and a residential area on the south. MD 176 intersects MD 652 (Old Telegraph Road) and WB&A Road and passes the Thomas A. Dixon Aircraft Observation Area. The highway gains a median and reaches the eastern end of its portion of Airport Loop at its junction with MD 162 (Aviation Boulevard) at the southern edge of Ferndale. East of MD 162, MD 176 has an incomplete partial cloverleaf interchange with I-97. The missing movement, from southbound I-97 to MD 176, is handled via MD 162. The state highway becomes undivided just before reaching its eastern terminus at MD 648 (Baltimore–Annapolis Boulevard) in Glen Burnie. This intersection is adjacent to one of two southern ends of the Baltimore Light Rail; the terminal station, Cromwell Station / Glen Burnie, is accessed via MD 648. The junction is also next to the northern end of the Baltimore & Annapolis Trail. The eastern leg of the intersection is 8th Avenue N.W.〔〔 MD 176 is a part of the National Highway System as an intermodal connector between MD 162 and I-97.〔〔 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「Maryland Route 176」の詳細全文を読む スポンサード リンク
