- Indawo: Balboa, Panama
- Ubude obude: 1.654 m
- Ububanzi beBridge : 10.4 m
- Ukuvulwa: Oktobha 12, 1962
KwiRiphabhliki yasePanama kukho ibhuloho yendlela eyahlukileyo ewela indlela yePanama Canal kuLwandle lwasePacific e- Balboa kwaye inxalenye yePan-American Highway. Ekuqaleni kwakubizwa ngokuba yiThecher Ferry Bridge (i-Thatcher's Ferry Bridge), kodwa kamva wabizwa ngokuba yiBridge ye-Two Americas (Puente de las Américas).
Ulwazi oluqhelekileyo malunga nezokhenketho
Ukufumanisa kwenzeka ngo-1962, kwaye indleko yokwakha yayingaphezu kwezigidi ezingama-20 zeedola. Kuze kube ngo-2004 (kude kube yilapho iBridge ye-Century yakhiwe), bekuyiyona bhuloho kuphela engqalileyo ehlabathini edibanisa amazwekazi amabini aseMerika.
Ibhuloho yamaMerika amabini yenzelwe kwaye yakhiwe yinkampani yaseMerika ebizwa ngokuthi iSverdrup & Parcel. Into enikwe yona iye yavumela ukwandisa ubuninzi beemoto eziwela ngapha kwezala. Ngaphambi koko, kwakukho i-drawbridges ezi-2 ezinamandla aphantsi. Eyokuqala kwezi ziyi-bridge yebhasi yemoto kwi- Miraflores Gateway , kwaye yesibini kwisebe laseGatun.
Imbali yendalo
Emva kokuba iPanama Canal yakhiwe, kwavela ukuba izixeko zasePanama kunye neColon zahlukana nelizwe. Le ngxaki ingakhathazeki kuphela ngabahlali bendawo, kodwa noorhulumente. Inani leemoto ezinqwenela ukuwela i-ismmus nazo zanda. Ngenxa yesigxina esipheleleyo seenqanawa kwiidrafriji, iimfesane zengxama ezinde zenziwe. Kwaye kwaqaliswa izitya ezininzi, kodwa azikwazanga ukulayisha indlela.
Emva koko, ulawulo lwePanama lugqiba ukwakha ibhuloho elingenangqiqo, kwaye ngo-1955 wasayinwa iSivumelwano esiDumileyo saseRonon-Eisenhower.
Ukwakhiwa kweBridge eBrazil eMelika kuye kwaqala ngo-1959 ngumbhiyozo oya kwi-ambassador yase-United States uJulian Harrington kunye noMongameli u-Ernesto de la Guardia Navarro.
Inkcazelo yokwakha
Ibhuloho yamaMerika amabini inempawu zobugcisa obuhle kakhulu: yenziwe ngekrakra kunye nokwakhiwa kweseyile ye-steeltilever, apho i-overhead yenziwe ngohlobo lwe-arch. Ubude obude bebhoreji ngu-1654 m, inani lezithuba ezivela kwenkxaso kuya kwi-14 m, eyona nto ingundoqo yi-344 m kwaye ixhunywe ngophawu (inxalenye ephambili yendawo ephambili), eneesayizi ezingama-259 m.
Ingongoma ephakamileyo yesakhiwo ingama-117 m ngaphezu kweselwandle. Ngokubhekisele kwi-lumen phantsi kwe-span eyintloko, kummandla we-61.3 wamitha. Ngenxa yesi sizathu, zonke iinqanawa ezidlula ngaphantsi kwebhuloho zinemimiselo ephakamileyo yokuphakama.
Ibhuloho ukusuka kumaphelo alo amabini kunemizila ebanzi eqinisekisa ukungena okukhuselekileyo kwaye uphume kuyo, kwaye ihlukaniswe kwiinqanaba ezine. Kwakhona kuneendlela ezihamba ngeenyawo kunye nebhayisikili kulabo abafuna ukuwela umnqweno.
Ibhuloho yamacandelo amabini aseMerika ePanama yinto ekhangelekayo, ngakumbi ebusuku, xa ukhanyiswa ukusuka kumacala onke. Umbono ogqithiseleyo kuwo uvula kwidonga lokubona, elisentabeni, kufuphi nomsele. Umbono omuhle uya kuba kwakhona kwiqela le-yacht eBalboa , kwelinye leenqanawa ezininzi ezihamba apha.
Ukuba ufuna ukubona indlela iinqanawa zidlula ngaphantsi kwebhuloho, akumele ukhethe ixesha elithile kule: inani elikhulu leenqanawa lidlula ngaphantsi kwalo.
Ekuqaleni, iBrador yeeMerika ezimbini yawela ngaphezu kwee-9.5 zeemoto ngemini. Ngo-2004, kwandiswa, kwaye kwagqitywa kweemoto ezingaphezu kwama-35,000. Kodwa nangona lo mfanekiso wawungenako ukwanda kweemfuno, ngoko ngo-2010 iBridge ye-Century yakhiwa.
Ndingafika njani?
Ukuba unemoto, kulula ukuyifumana kwiBridge eBamerica ezimbini, ngenxa yoko kufuneka ulandele iNqanawa yasePan-American. Kwakhona ungathatha iteksi ukusuka kwiidolophu ezikufutshane, indleko ayikho ngaphezu kwe-20.
