The highway runs from I-95 in Arbutus east to Baltimore/Washington International Thurgood Marshall Airport (BWI Airport) in Linthicum. I-195, which is also known as Metropolitan Boulevard, is the main connection between the airport terminal and highways leading to Baltimore, Washington, and Annapolis, including I-95, MD 295, and I-97. The Interstate highway also has an interchange with MD 170, which forms part of the Airport Loop that provides access to various airport-related services. I-195 also links I-95 with Catonsville and the University of Maryland, Baltimore County (UMBC), via a westward continuation of Metropolitan Boulevard that is part of MD 166. I-195 was constructed in three sections. The first section was a connection between MD 295 and the airport. This segment was built as Maryland Route 46 and completed in 1951 shortly after the opening of the airport, which was originally named Friendship International Airport. The second segment was completed at the opposite end of the highway in the mid-1970s, connecting U.S. Route 1 (US 1) and I-95 with MD 166 and UMBC. The first two segments were connected when the portion between MD 295 and US 1 was constructed in the late 1980s. The whole length of the highway was completed and was marked as I-195 in 1990. ==Route description== I-195 begins at the western edge of its interchange with I-95. The freeway continues west as MD 166, which has a partial interchange for UMBC Boulevard, which leads to the UMBC campus, before ending next to a park and ride facility at Rolling Road, on which MD 166 continues north toward Catonsville. The I-95 interchange is a partial cloverleaf that has flyover ramps from northbound I-95 to westbound I-195 and from southbound I-95 to eastbound I-195. I-195 heads southeast as a four-lane freeway with a speed limit of across CSX's Baltimore Terminal Subdivision and meets US 1 at a four-ramp partial cloverleaf interchange. The highway crosses over I-895 (Harbor Tunnel Thruway) with no access and curves south on a viaduct to cross the Patapsco River, where the freeway passes from Baltimore County to Anne Arundel County, and the Amtrak Northeast Corridor, which also carries MARC's Penn Line. I-195 parallels the railroad south to its partial cloverleaf interchange with MD 295 (Baltimore–Washington Parkway), which contains a flyover ramp from southbound MD 295 to eastbound I-195.〔〔 I-195 curves southeast and passes under the BWI Trail ahead of its partial cloverleaf interchange with MD 170 (Aviation Boulevard), also known as the Airport Loop. The Airport Loop provides access to long-term parking lots, the consolidated rental car facility, hotels, cargo and general aviation facilities, and the BWI Rail Station. The circumferential highway also provides indirect access to I-97 for traffic heading to Annapolis or the Chesapeake Bay Bridge. The Interstate's speed limit drops to as it arrives at its eastern terminus at the entrance to BWI Airport. The eastbound roadway continues southeast into the airport proper, where it features a left exit for the hourly parking garage and then splits into two roadways for arriving and departing flights. After the two roadways—arriving flights on the lower level and departing flights on the upper level—loop between the terminal and the hourly parking garage, the roadways merge. The westbound direction of I-195 heads northwest from the airport after it issues a ramp toward long-term parking and a U-turn toward the terminal.〔〔 Like all Interstates, I-195 is a part of the National Highway System for its entire length.〔 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 195 (Maryland)」の詳細全文を読む スポンサード リンク
