'''The Stack''' is a [colloquialism](/source/colloquialism) used to describe the symmetrical, four-level [stack interchange](/source/stack_interchange) in [Phoenix, Arizona](/source/Phoenix%2C_Arizona) that facilitates movements between [Interstate 17](/source/Interstate_17)/[U.S. Route 60](/source/U.S._Route_60_in_Arizona) and [Interstate 10](/source/Interstate_10_in_Arizona).<ref>{{cite web| url = http://kjzz.org/news/traffic/terms| title = The Stack Interchange| publisher = KJZZ| access-date = 2008-03-18}}</ref>

==Description==
In 2006, the Stack interchange saw an average of 235,000 cars pass through it daily on [Interstate 10](/source/Interstate_10_in_Arizona) eastbound and westbound and an average of 120,000 cars on northbound and southbound [Interstate 17](/source/Interstate_17).<ref>{{cite web| url = http://tpd.azdot.gov/data/documents/SHSAADT0707.xls| archive-url = https://web.archive.org/web/20160303212134/http://tpd.azdot.gov/data/documents/SHSAADT0707.xls| url-status = dead| archive-date = 2016-03-03| title = Arizona AADT| publisher = ADOT| access-date = 2008-03-18}}</ref> The interchange constitutes exit 200A on Interstate 17 and exits 143A and 143B on [Interstate 10](/source/Interstate_10_in_Arizona). Access is provided in all directions, and there are no direct [HOV lane](/source/HOV_lane) connections. Interstate 17 has two [frontage road](/source/frontage_road)s running both southbound and northbound through the interchange known as Black Canyon Highway.

[US 60](/source/U.S._Route_60_in_Arizona) runs concurrently with I-17 throughout this interchange.

==History==
The stack was the [Phoenix Metropolitan Area](/source/Phoenix_Metropolitan_Area) and Arizona's first four-level [stack interchange](/source/stack_interchange) upon its completion in 1990 and one of the last portions of I-10 in Arizona to be completed.<ref>{{cite web

==Congestion==
In a 2007 study by ''[Forbes](/source/Forbes)'', the Stack ranked number twelve in the United States in terms of delays with 16 million hours of delays each year. This is much better than the [Mini Stack](/source/Mini_Stack), which logged 22 million hours of delays, the fourth-worst in the nation.<ref>{{cite news|url=https://www.forbes.com/2007/06/11/traffic-highways-interstates-biz-logistics_cx_rm_0611traffic_slides.html |title=America's 12 Worst Traffic Traps |work=Forbes |access-date=2010-09-17 |date=2007-06-11 |archive-url=https://web.archive.org/web/20160420101034/http://www.forbes.com/2007/06/11/traffic-highways-interstates-biz-logistics_cx_rm_0611traffic_slides.html |archive-date=April 20, 2016 |url-status=dead }}</ref>
