El Iibhulorho ezisixhenxe zeMiles (Iibhulorho ezisixhenxe zeMile) sisakhiwo esifanekisayo se Iifayile zaseFlorida ejikeleza kulwandle oluvulekileyo, edibanisa uthotho lweziqithana ezathi ngexesha lokugqitywa kwayo ngo-1982, yayiyeyona bhulorho inde eqhubekayo ehlabathini, kwaye kungoku nje yenye yeebhulorho ezinde eMelika.
Ngokwenene ziqulathe iibhlorho ezimbini kwindawo enye. Ibhulorho endala, eyakhiwa ukusuka ngo-1909 ukuya ku-1912 njengenxalenye yomgaqo kaloliwe kwaye yabanengxaki enkulu ngexesha lenkanyamba yoSuku lwaBasebenzi ngo-1935, kodwa yabuyiselwa ekusetyenzisweni kweemoto.
Emva koko, ngeNkanyamba uDonna ngo-1960 kunye nomonakalo omtsha wolwakhiwo, kwathathwa isigqibo sokwakha ibhulorho entsha. Le bhulorho iqhagamshela isitshixo sikaK Knight (inxalenye yesixeko saseMarathon) kunye neKhitshi leDuck elincinci kwiiLitshi ezisezantsi.
Ibhulorho entsha yibhokisi ye-girder yesakhiwo eyakhiwe kwizinto zangaphambili, izinto zekhonkrithi esele zixinaniswe, zenza i-440 spans. Kufuphi neziko, ibhulorho inyuka ngobude beemitha ezingama-65 (20 m) ukuphakama kunika imvume yobuchwephesha bokuhamba kwenqanawa. Indawo eseleyo yebhulorho isondele kakhulu kumphezulu wamanzi. Ibhulorho entsha enganqamliyo iPigeon Key.
Ubude bebhulorho entsha bubude obuziimitha ezingama-35,862 okanye iimayile eziyi-10,931 (i-6,79 km), kwaye imfutshane kunaleyo yantlandlolo. Rhoqo ngo-Epreli ibhulorho ivaliwe malunga neeyure ezi-10,93 kwiMarathon ebandakanya iimbaleki ezili-2,5 ezilungiselelwe ukukhumbula ukwakhiwa ngokutsha kweFlorida Keys Bridge.
I-Seven Mile Bridge yenzelwe u-Figg kunye no-Muller Ingenieros. Isakhiwo sigqityiwe kwiinyanga ezintandathu phambi kweshedyuli kwaye siphumelele amabhaso asibhozo, kubandakanya neBhaso eliKhulu lokuGcina iindleko kwi-Federal Highway Administration.
