State Route 87 (SR 87), locally called Highway 87 or the Guadalupe Freeway, is a north–south state highway entirely within San Jose, California, United States, with as exception a very small portion that is part of the unincorporated county. Its name was changed from Guadalupe Parkway (although signs still refer to it as the Guadalupe Parkway) in 2004 after its entire constructed length was upgraded to a freeway. For most of its length, especially in Downtown San Jose, the highway follows the course of the Guadalupe River. Its southern terminus is at State Route 85 (West Valley Freeway), and its northern terminus is at U.S. Route 101 (Bayshore Freeway) just north of San Jose International Airport. Unusually, it crosses over Interstate 880 (Nimitz Freeway) without an interchange, making it the only point in California where two freeways cross without a connection. ==Route description== This route is part of the California Freeway and Expressway System.〔(CA Codes (shc:250-257) )〕 A Guadalupe Parkway connection between Downtown San Jose and the present day US 101 had existed since the early 1960s; the road channeled traffic between the Bayshore Freeway and ramps that connected directly to Market Street. However, construction on a freeway over the same path and southward beyond Downtown began a decade later and stretched across 30 years. The first stage of the Highway 87 freeway, its 4-level interchange with I-280, replaced an old downtown neighborhood in the early 1970s. A ramp to Julian Street, north of the interchange with I-280, was completed in the mid-1970s. The freeway extension north to Taylor Street was completed in the 1980s. The southern part, from I-280 to Highway 85, was opened to Almaden Expressway in 1992 and to Highway 85 in 1993, built in conjunction with the construction of a light rail line. Local-express lanes were constructed along this segment, the Northbound segment running from Interstate 280 to Julian Street and the Southbound extension from Interstate 280 to Alma Avenue. At Highway 87's northern terminus, its 3-level interchange with Highway 101 and North First Street was completed in 1992. Finally, with all grade-level intersections replaced by grade separations, construction of the six-lane freeway between Taylor Street and the Highway 101/North First interchange was completed in 2004, with the final ramps at the Skyport interchange opening in 2005. The widening of the southern segment, from Taylor Street to Highway 85, to six lanes was completed in 2007. The right-of-way for Highway 87 south of Interstate 280 includes two tracks for the Guadalupe line of the Santa Clara Valley Transportation Authority light rail system. Stations are accessible from the streets via staircases and elevators. Beyond 87's terminus, the line continues southeastward in the median of Route 85. 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「California State Route 87」の詳細全文を読む スポンサード リンク
