'''卑詩省91號公路'''是[[加拿大]][[卑詩省]][[大溫哥華地區]]一條主要[[高速公路]]，全長23公里<ref name="LKI">{{cite web|title=British Columbia Landmark Kilometre Inventory|url=https://www2.gov.bc.ca/assets/gov/driving-and-transportation/transportation-infrastructure/engineering-standards-and-guidelines/traffic-engineering-and-safety/highway-safety/lki/lki_bc_201607.pdf|page=399-402|publisher=卑詩省政府 / Cypher Consulting|date=2017-01-05|accessdate=2018-09-20|archive-url=https://web.archive.org/web/20181107130311/https://www2.gov.bc.ca/assets/gov/driving-and-transportation/transportation-infrastructure/engineering-standards-and-guidelines/traffic-engineering-and-safety/highway-safety/lki/lki_bc_201607.pdf|archive-date=2018-11-07|dead-url=yes}}</ref>，連接[[三角洲區]]和[[列治文]]，兩端皆與[[卑詩省99號公路|99號公路]]交接。
== 走 路 線==91號公路南端位於三角洲區東南部，與[[卑詩省99號公路|99號公路]]交匯，自此往北延2公里與10號公路交匯，再往北途經兩個交匯處後與北三角洲大道（{{lang|en|Nordel Way}}）交匯。駕駛人 士 可經該交匯處通往[[卑詩省17號公路|17號公路]]，再沿該公路通往[[卑詩省1號公路|1號公路]]。91號公路隨之途經[[阿力克斯·菲沙橋]]跨越[[菲沙河]]南支流後抵達安那西斯島（{{lang|en|Annacis Island}}），並於島上設一交匯處。此段91號公路的對外掛牌方向為南北向，正式名稱為「安那西斯公路」（{{lang|en|Annacis Highway}}）<ref name="85to88">{{cite web|title=Summer Traffic Volumes on Provincial Highways in British Columbia 1985 to 1988|url=https://www.th.gov.bc.ca/trafficData/legacy/traffic_volumes/historic/1985_to_1988_Summer_Traffic_Volumes.pdf|page=58-59|publisher=卑詩省政府|accessdate=2018-09-20|archive-date=2018-09-20|archive-url=https://web.archive.org/web/20180920195758/https://www.th.gov.bc.ca/trafficData/legacy/traffic_volumes/historic/1985_to_1988_Summer_Traffic_Volumes.pdf|dead-url=no}}</ref>， 但 此名並不被民眾廣泛使用。
公路隨後跨橋從安那西斯島通往[[魯魯島]]，隨即與91A公路交匯並進入列治文。公路自此往 西延10 西10 公里，途經四個交匯處後再度與99號公路交匯，而91號公路亦到此為止<ref name="LKI"/><ref>{{cite web|author= |title= Official Numbered Routes in British Columbia - Highway 91|url= http://www.th.gov.bc.ca/publications/planning/numbered_routes.htm#91|date=2008-05-28|work= |publisher= BC Ministry of Transportation|accessdate= 7 September 2009|archive-date= 2014-07-09|archive-url= https://web.archive.org/web/20140709115652/http://www.th.gov.bc.ca/publications/planning/numbered_routes.htm#91|dead-url= no}}</ref>，並駁上赤楊橋大道（{{lang|en|Alderbridge Way}}）通往列治文的中心地帶。91號公路列治文段的對外掛牌方向為東西向，正式名稱為「列治文公路」（{{lang|en|Richmond Freeway}}），但民眾 亦 比較 常稱 之 為「東西連接路」（{{lang|en|East-West Connector}}）。
== 歷史緣由==
為配合[[溫哥華]]舉辦[[1986年世界博覽會]]，省府於1980年代在大溫地區進行數項基建工程，其中一環為興建91號公路。包括[[阿力克斯·菲沙橋]]，連接北三角洲和魯魯島東部的91號公路南北向路段於1986年完成<ref name="85to88"/><ref>{{cite web|title=Frontier to Freeway - A Short Illustrated History of Roads and Highways in British Columbia|url=https://www2.gov.bc.ca/assets/gov/driving-and-transportation/reports-and-reference/reports-and-studies/frontier_to_freeway.pdf|publisher=卑詩省政府|page=30|accessdate=2018-09-20|archive-date=2018-11-07|archive-url=https://web.archive.org/web/20181107121208/https://www2.gov.bc.ca/assets/gov/driving-and-transportation/reports-and-reference/reports-and-studies/frontier_to_freeway.pdf|dead-url=no}}</ref>。91號公路當時亦沿昆士堡連接路（{{lang|en|Queensborough Connector}}）穿越[[新西敏市|二埠市]]位於魯魯島上的昆士堡社區，再沿昆士堡橋跨越菲沙河北支流後抵達二埠市區為止。列治文市以内的91號公路東西向路段則於1989年完成，昆士堡連接路和昆士堡橋隨之改編為91A公路。
省政府規劃91號公路時並未與三角洲區政府就72大道交匯處的設計達成共識，因此公路開通時在72大道只以交通燈平交， 留 等 待日後才改建為立體交匯處。然而此交通燈平交路口在 公路 通車多年後仍未改建，導致北行往阿力克斯·菲沙橋的交通經常堵塞於此。加拿大聯邦政府和卑詩省政府曾於2003年宣布合共預留1千萬加元將此燈位改建成立交道<ref>{{cite web|author= |title= $211 million Canada-BC investment at BC lower Mainland crossings|url= http://www.infc.gc.ca/media/news-nouvelles/bif-fsif/2003/20030305vancouver-eng.html#bg|date= 30 December 2009|work= |publisher= Infrastructure Canada|accessdate= 7 September 2009|deadurl= yes|archiveurl= https://web.archive.org/web/20110706181820/http://www.infc.gc.ca/media/news-nouvelles/bif-fsif/2003/20030305vancouver-eng.html#bg|archivedate= 2011年7月6日}}</ref>，但省府和三角洲區政府仍未達成協議，計劃因此未有落實 進行 ， 而 預留的款項 亦 也 已 改 用 作 在 其它用途；省政府更於2011年表示無意改建此平交道<ref>{{cite web|author= Dave White|title= Delta wants federal cash for highways|url= http://www.news1130.com/news/local/article/271782--delta-wants-federal-cash-for-highways|date= 29 August 2011|work= |publisher= News 1130|accessdate= 3 September 2011|deadurl= yes|archiveurl= https://web.archive.org/web/20120323154613/http://www.news1130.com/news/local/article/271782--delta-wants-federal-cash-for-highways|archivedate= 2012年3月23日}}</ref>。省府終在2016年6月宣布斥資3千萬元將此燈位改建成立交道<ref>{{cite web|url=http://www.news1130.com/2016/06/08/delta-interchange-construction-announcement/|title=Provincial government announces new interchange for 72nd Ave at Hwy 91|date=8 June 2016|publisher=News 1130|accessdate=2018-09-20|archive-date=2018-08-29|archive-url=https://web.archive.org/web/20180829124114/https://www.news1130.com/2016/06/08/delta-interchange-construction-announcement/|dead-url=no}}</ref><ref name="72nd_int">{{cite web|title=Highway 91 at 72nd Avenue - Interchange Project|url=http://www2.gov.bc.ca/gov/content/transportation/transportation-infrastructure/projects/highway91-72avenue|website=Ministry of Transportation and Infrastructure|publisher=Province of British Columbia|accessdate=January 4, 2017|archive-date=2018-10-11|archive-url=https://web.archive.org/web/20181011085941/https://www2.gov.bc.ca/gov/content/transportation/transportation-infrastructure/projects/highway91-72avenue|dead-url=no}}</ref><ref>{{cite web|last1=Smith|first1=James|title=Construction to start on interchange in Delta at Highway 91 and 72nd Avenue|url=http://www.peacearchnews.com/news/401581825.html|publisher=Peace Arch News|date=November 16, 2016|accessdate=January 4, 2017|archive-date=2017-01-04|archive-url=https://web.archive.org/web/20170104233757/http://www.peacearchnews.com/news/401581825.html|dead-url=no}}</ref>；項目於2016年末動工，而交匯處則於2018年8月12日落成啓用，91號公路自此全線達致高速公路規格<ref>{{cite news |last1=Bernard |first1=Renee |last2=James |first2=Tim |date=August 12, 2018 |title=Overpass in Delta replaces traffic lights on Highway 91 |url=https://www.news1130.com/2018/08/12/overpass-delta-replaces-traffic-lights-highway-91/ |publisher=News 1130 |accessdate=August 13, 2018 |archive-date=2018-08-14 |archive-url=https://web.archive.org/web/20180814103132/https://www.news1130.com/2018/08/12/overpass-delta-replaces-traffic-lights-highway-91/ |dead-url=no }}</ref>。
