Ngitshele ngezinhlobo zemigwaqo ehlukahlukene e-USA?
Uhlelo lwemigwaqo yomphakathi e-United States of America ngokuyinhloko lwakhiwa Imigwaqo Emikhulu Nemigwaqo Yendawo. I-United States Department of Transportation's Federal Highway Administration (FWHA) ihlukanisa imigwaqo ngokusekelwe emisebenzini eyenziwe ngokusekelwe ezintweni ezinjengezilinganiso zejubane, ubude bomzila kanye nokuhlukaniswa. Ngokusekelwe emisebenzini yomgwaqo singahlukanisa imigwaqo ngezigaba ezilandelayo. 1. Izinkomo Imigwaqo Emikhulu Nemigwaqo Emikhulu 2. Izingelosi Eminye Imithambo 3. Izindaba Ezinhle Abaqoqi 4. Izidakamizwa Abantu bendawo  Uhlelo lwe-interstate luhamba phambili ohlelweni lokuhlukanisa imisebenzi yemigwaqo. Zihlanganisa Imigwaqo Emikhulu Nemigwaqo Emikhulu enemingcele yesivinini ephakeme kakhulu futhi evumela ukuhamba ibanga elide ngaphandle kokuphazanyiswa okuningi. Zakhiwa kusetshenziswa izindinganiso eziqondile, izimpawu kanye nokucatshangelwa kokuphepha. Ngezinye izikhathi zibizwa nangokuthi imigwaqo ye-Arterial njengoba zinikeza ukuxhumana okubalulekile ezifundeni zaseMelika. I-Interstate 95 noma i-I-95 iyisibonelo somgwaqo omkhulu onjalo ogwini olusempumalanga ye-United States ogeleza usuka eFlorida uye eMaine. Uhlelo lwe-Principal Arterial lubuye luqukethe Imigwaqo emikhulu yase-US, enikeza ukuxhumana ezifundeni ezingenayo i-Interstate ukusekela ukuhamba.  Eminye imigwaqo emikhulu ihlanganisa imigwaqo emikhulu nemigwaqo emikhulu eyenezela ohlelweni lwe-Interstate oluchazwe ngenhla. Banemikhawulo yejubane ephansi kancane. Ngokuvamile zixhuma amadolobha nezindawo ezisemadolobheni. Zibheke njengezindlela ezinkulu ezincane. Isibonelo, iNorth Carolina Highway 55 (NC-55) iyindlela eyinhloko yomgwaqo omkhulu ohlanganisa izindawo eziningi zesifunda nezasemadolobheni esifundazweni saseNorth Carolina.  Ama-collector abalulekile ekuxhumaniseni abantu basemadolobheni abasebenzisa imigwaqo yasendaweni nemigwaqo emikhulu yamazwe lapho kusebenza khona. Zinokuphazamiseka okwengeziwe futhi zimfushane ngobude. Futhi zinemikhawulo yejubane ephansi (30-35 mph). Lezi zingase zihlanganise imigwaqo emikhulu kaHulumeni exhumanisa imigwaqo yendawo nemigwaqo emikhulu.  Okokugcina, imigwaqo yasendaweni inikeza ukuxhumana phakathi kwemiphakathi, izifunda, amapulazi nezinye izindawo zendawo. Zakha ingxenye enkulu yohlelo lwemigwaqo yase - United States.
