Canada Yizwe elikhulu kunawo wonke eNyakatho Melika ngendawo yomhlaba, okwesibili emhlabeni jikelele. Yaziwa umhlaba wonke ngobubanzi bayo bendawo, inhlanganisela yamasiko ehlukile, nomlando onezinhlobonhlobo, iCanada iyindawo enkulu yezivakashi futhi ingenye yamazwe acebe kakhulu emhlabeni.
Mayelana nalokhu, leli lizwe elikhulu linengqalasizinda ebanzi yemigwaqo kuyo yonke indawo yalo. Enye yazo yi IDempster Highway okuwumgwaqo omkhulu onqamula ugwadule olungaphansi kwe-arctic enyakatho yeYukon Territory ubheke enyakatho-ntshonalanga yeCanada.
Phakathi nezinyanga zasebusika, umgwaqo omkhulu uhamba ibanga elingaphezulu kwamakhilomitha ayi-194 (amamayela ayi-121) ukuya eTuktoyaktuk, ogwini olusenyakatho neCanada, kusetshenziswa izingxenye ezibandayo zomfula iMackenzie River njengomgwaqo omkhulu weqhwa (iTuktoyaktuk Winter Route).
Umgwaqo omkhulu unqamula uMfula iPeel noMfula iMackenzie usebenzisa inhlanganisela yesevisi yesikebhe sonyaka namabhuloho eqhwa.
Umgwaqo omkhulu uqala cishe ngamakhilomitha angama-40 (25 miles) empumalanga yeDawson City, eYukon kuKlondike Highway futhi unwebisa amakhilomitha angama-736 (457 miles) ukuya e-Inuvik.
Iningi lomgwaqo lilandela umkhondo wesihlibhi sezinja. Lo mgwaqo uqanjwe ngoMhloli uWilliam John Duncan Dempster weMontana Cavalry okwathi njenge-ejenti esencane wayejwayele ukuhamba ngezinja esuka eDawson City eya eFort McPherson.
U-Inspector Dempster namanye ama-ejenti amabili athunyelwa kozotakula ngoMashi 1911, ukuyothola uMhloli u-Francis Joseph Fitzgerald kanye nabesilisa bakhe abathathu abafikanga eDawson City. Babelahlekile endleleni, futhi bafa ngenxa yokuchayeka nendlala. Izidumbu zikaDempster namadoda akhe zatholakala ngoMashi 3, 22.
Ngo-1958, uhulumeni waseCanada wenza isinqumo esingumlando sokwakha umgwaqo ongamakhilomitha angama-671 (417-mile) odabula ugwadule lwase-Arctic olusuka eDawson City luye e-Inuvik. Futhi ukuthi ukuhlola uwoyela negesi kwakuchuma eMackenzie Delta kanti idolobha lase-Inuvik lalisakhiwa.
IDempster Highway ivulwe ngokusemthethweni ngo-Agasti 18, 1979, ivulwa ngemizila emibili, kwavela ubhuqu, kunoma yisiphi isiteshi somgwaqo omkhulu esihamba amakhilomitha angama-671 (417 miles) ukusuka eKlondike Highway ngaseDawson City kuya eFort McPherson nase-Arctic. IRed River (manje eyiTsiigehtchic) Ezifundeni zaseNyakatho-ntshonalanga.
Idizayini yomgwaqo ihlukile, ikakhulukazi ngenxa yezimo zomzimba ezinzima lapho ihlupheka khona. Umgwaqo uqobo uhleli phezu kuka-berm wamatshe ukuze uhlukanise iqhwa elingaphansi komhlaba. Ubukhulu besendlalelo segravel busuka ku-1,2 m (3 ft 11 in) kuye ku-2,4 m (7 ft 10 in) kwezinye izindawo. Ngaphandle kwephedi, iqhwa liyancibilika futhi indlela ingacwila emhlabathini.
