A very small portion between the Curtner Avenue exit and the Capitol Expressway Auto Mall exit is 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 SR 85, and its northern terminus is at U.S. Route 101 (US 101) just north of San Jose International Airport. Unusually, it crosses over Interstate 880 (I-880) without an interchange.[3] Route descriptionSR 87 has carpool lanes for its entire length. SR 87 begins at SR 85 in southern San Jose. VTA light-rails run parallel to this freeway from SR 85 to I-280. After intersecting CR G21, SR 87 runs through a small pass in Communications Hill. SR 87 intersects I-280 in southwestern Downtown San Jose, then runs parallel to the western border of Downtown San Jose. Unusually, SR 87 crosses above I-880 without an interchange. Located between Taylor Street and Skyport Drive, the site where the two freeways cross has two restrictions that prevent the construction of any connecting ramps. First, because of its proximity to the runways at San Jose International Airport, any elevated ramps running above the SR 87 mainline would interfere with flight paths. Second, tunneling underneath would make a significant environmental impact to the nearby Guadalupe River.[3] Drivers from SR 87 to I-880 and vice versa have to use First and Taylor Streets to get on the freeways. SR 87 runs east of the Mineta San Jose International Airport before terminating at US 101 in northwestern San Jose. This route is unconstructed from US 101 to SR 237 in Santa Clara, legislatively defined to run north from US 101 through suburban San Jose and Santa Clara, terminating at SR 237, as this route is defined as (a) Route 85 in the vicinity of Santa Teresa Boulevard to Route 101 in the vicinity of Guadalupe River and (b) San Jose easterly of Route 101 to Route 237.[4] SR 87 is part of the California Freeway and Expressway System,[5] and except for a small portion south of I-280 is part of the National Highway System,[6] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.[7] In 2014, SR 87 had an annual average daily traffic (AADT) of 88000 at US 101, and 176000 between I-280 and CR G8, the latter of which was the highest AADT for the highway.[8] SR 87 BikewayThe SR 87 Bikeway is a {{convert|4.1|mi|km|adj=mid|-long}} pedestrian and bicycle path that runs alongside portions of SR 87. The path was constructed by Caltrans as part of the final phase of the SR 87 project. It opened to the public on September 1, 1993.[9] The north end of this path is at Willow Street (north of the Alma Street exit). The south end is at the 87-85 interchange. Along this route, the path runs along the east side of the freeway. The path diverges from the freeway for {{convert|0.7|mi|km}} near Curtner Avenue and again for {{convert|1.1|mi|km}} near Capitol Expressway, running along city streets near the highway. This path provides connections for other trails in the area, including the Guadalupe River Trail and Los Gatos Creek Trail.[10] History{{more footnotes|date=June 2016}}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 SR 87 freeway, its 4-level interchange with I-280, replaced an old downtown neighborhood in the mid 1960s. 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 May 1988. Construction of SR 87 in the 1980s is shown in this photo. The southern part, from I-280 to SR 85, was opened to Almaden Expressway in September-October 1992 and to SR 85 in August 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 I-280 to Julian Street and the Southbound extension from I-280 to Alma Avenue. At SR 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 began in the late 1990s 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. Two lanes are regular traffic and one lane is an HOV lane.[11] The right-of-way for SR 87 south of I-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 SR 85. SR 87, as once defined legislatively, would have extended from its current northern terminus, skirting the edge of San Francisco Bay as the Bayfront Freeway to San Francisco. This would have provided an eastern bypass to US 101 along the Peninsula (US 101 itself being originally a bypass to El Camino Real along the Peninsula). The route would have ended at SR 480 (the Embarcadero Freeway) practically underneath the Bay Bridge, and it would also have connected to the approaches to the unconstructed San Francisco Bay Southern Crossing. Along with SR 61, a similar project on the eastern shore of the Bay, this portion of SR 87 was abandoned due to local opposition to the project that would have destroyed a nearly pristine wildlife habitat. In 1980, the route was truncated to end at SR 237.[2] A resolution of the state legislature in 2007 named a section of this highway (between I-280 and Julian Street/Santa Clara Street) the Lewis E. Platt Memorial Highway (honoring the late chairman, president and chief executive officer of Hewlett-Packard who successful campaigned for local ballots to fund transportation improvements), and required that signage be paid by private donations.[12] FutureThe High-occupancy vehicle (HOV) lanes on SR 87 are proposed to be converted into express lanes, lanes that require tolls to use. The date of conversion isn't certain, but Plan Bay Area plans for the project to be completed by 2018 and the California Department of Transportation (CalTrans) plans it by 2020.[13] CalTrans' post-25 year concept also proposes an additional express lane in each direction.[14] Exit list{{CAinttop|exit|length_ref=[17] |exit_ref=[15] |county=Santa Clara |location=San Jose }}{{CAint|exit |mile=0.00 |exit=1 |road={{Jct|state=CA|SR|85|name1=West Valley Freeway|city1=Gilroy|city2=Mountain View}} |notes=Southbound exit and northbound entrance; signed as exits 1A (south) and 1B (north); south end of SR 87; SR 85 north exit 5A, south exit 5B }}{{CAint|exit |type=incomplete |mile=0.00 |exit=1C |road=Santa Teresa Boulevard |notes=Southbound exit and northbound entrance }}{{CAint|exit |mile=1.34 |exit=1D |road=Capitol Expressway Auto Mall (CR G21) |notes=Signed as exit 1 northbound }}{{CAint|exit |mile=2.83 |exit=3A |road=Curtner Avenue |notes=Signed as exit 3 northbound }}{{CAint|exit |type=incomplete |mile=3.35 |exit=3B |road=Almaden Expressway (CR G8) |notes=Southbound exit and northbound entrance }}{{CAint|exit |type=incomplete |mile=4.12 |exit=4 |road=Alma Avenue |notes=Southbound exit and northbound entrance }}{{CAint|exit |mile=5.15 |exit=5 |road={{jct|state=CA|I|280|to2=yes|I|680|city1=San Francisco|city2=Sacramento}} |notes=I-280 exit 3A }}{{CAint|exit |mile=5.56 |exit=6A |road={{jct|state=CA|SR|82|road=San Carlos Street}} |notes=Signed as exit 6 northbound, Former SR 82 }}{{CAint|exit |type=incomplete |mile=6.10 |exit=6 |road=Santa Clara Street |notes=Northbound exit only }}{{CAint|exit |mile=6.10 |exit=6B |road=Julian Street |notes=Signed as exit 6 northbound }}{{CAint|exit |type=closed |mile= |exit= |road=Market Street, Coleman Ave |notes=Closed in 2002 during construction of northern freeway segment; was southbound exit and northbound entrance }}{{CAint|exit |mile=6.80 |exit=7 |road=Taylor Street |notes=Taylor Street forms a single-point urban interchange (SPUI) over Highway 87.
