Ngasekupheleni kukaMashi walo nyaka, ngenxa yoqhekeko olunwebeka ngamamitha amabili emasontweni amabili, izikhulu zoMnyango Wezokuthutha waseSeattle (SDOT) zavala isiminyaminya eWest Seattle Bridge.
Nakuba izikhulu ze-SDOT zizama ukusimamisa ibhuloho futhi zinquma ukuthi ibhuloho lingasindiswa yini noma uma ibhuloho kufanele lishintshwe ngokuphelele, zacela iseluleko kumklami mayelana nokushintshwa kwebhuloho., Uma kwenzeka manje sesikwazi ukulungisa isikhathi esifushane ukuze siphinde sivule ibhuloho ngokushesha ngangokunokwenzeka, kodwa eminyakeni embalwa ezayo, ukusekelwa kwedizayini kusadingeka ukuze kushintshwe ibhuloho.“Inani lenkontileka lisukela ku-US$50 kuya ku-US$150 million.
Ekuqaleni, i-New York City Qualification Requirements (RFQ) yezinkampani zobunjiniyela ibonakala ilinganiselwe kwezinye izindlela zokuvala ibhuloho.Nokho, njengoba ukwesekwa komphakathi kwanda, unjiniyela womphakathi osewathatha umhlalaphansi u-Bob Ortblad naye wavumela iDolobha laseNew York ukuthi lifake ezinye izindlela zomhubhe ku-RFQ.Idolobha laseNew York lenze isithasiselo ekhasini lemibuzo, elithi: "Ezinye izindlela zizohlolwa njengengxenye yenkontileka, okuhlanganisa kodwa kungagcini nje ngomhubhe kanye nezinketho zokuxhumanisa ukuguqulwa komsindo."
Kuyathakazelisa ukuthi ngaphambi kokuba ekugcineni banqume ukuba yiWest Seattle Bridge yamanje, izikhulu zaseSeattle zacubungula ezinye izindlela ezingaba ngu-20 ngo-1979, okwaqedwa kuzo ezinye izindlela ezimbili zomhubhe.Angatholakala kwezinye Izindlela 12 kanye ne-13 ku-Final Environmental Impact Statement (EIS) ye-Spokane Street Corridor."Ngenxa yezindleko eziphakeme, isikhathi eside sokwakha kanye nokucekela phansi okukhulu, basuswa ekucabangeni."
Lokhu akusho ngaphandle kokuphikisa, ngoba ilungu lomphakathi elibambe iqhaza e-Harbour Island Machine Works laphawula nge-EIS: “Bagubhe umhubhe bawukhipha phansi ngenani eliphezulu kakhulu, futhi akekho onikeze izibalo.Manje, ithini inombolo engiyibuzayo, Noma bake bayizama?"
Umhubhe weshubhu ocwilisiwe (ITT) wehluke kakhulu kumhubhe we-SR 99.Lapho usebenzisa "i-Bertha" (umshini oyisicefe womhubhe) ukuze udale umhubhe we-99, umhubhe weshubhu ocwilisiwe waphonswa esizeni endaweni eyomile, bese uthuthwa futhi ucwiliswe ngaphansi kwamanzi afakwe emanzini.
I-Japan inemigudu engaphansi kwamanzi engu-25.Isibonelo sendawo esengeziwe se-ITT i-George Massey Tunnel ngaphansi komfula iFraser eVancouver, eBritish Columbia.Umhubhe wathatha isikhathi esingaphezudlwana kweminyaka emibili ukwakhiwa, kuhlanganise nezingxenye eziyisithupha zikakhonkolo, futhi wafakwa ngezinyanga ezinhlanu.U-Ortblad ukholelwa ukuthi umhubhe odlula e-Duwamish uzoba yindlela yokwakha esheshayo nethengekayo.Isibonelo, unikeze iphontoni engu-77 SR 520 edingekayo ukuze iwele iLake Washington - amaphontoni amabili nje acwile angawela i-Duwamish.
U-Ortblad ukholelwa ukuthi izinzuzo zemigudu emabhulohweni akubandakanyi nje ukunciphisa izindleko nokusheshisa isivinini sokwakha, kodwa nokuphila isikhathi eside kwenkonzo kanye nokumelana nokuzamazama komhlaba okuqinile.Nakuba ukushintshwa kwamabhuloho uma kwenzeka ukuzamazama komhlaba kusesengozini yokuncibilika kwenhlabathi, umhubhe unomoya ongathathi hlangothi ngakho-ke awuthintwa kakhulu izehlakalo zokuzamazama komhlaba ezinkulu.I-Ortblad ikholelwa nokuthi umhubhe unezinzuzo zokuqeda umsindo, ukungcola okubukwayo kanye nemvelo.Akuthintwa izimo zezulu ezimbi njengenkungu, imvula, iqhwa elimnyama nomoya.
Kukhona okucatshangwayo mayelana nemithambeka engumqansa engena futhi ephuma emhubheni nokuthi ikuthinta kanjani ukudlula kukajantshi okhanyayo.U-Ortblad ukholelwa ukuthi ukwehla ngo-6% kumiphumela iyonke kungenxa yokuthi ukwehla ngamamitha angama-60 kuyindlela emfushane kunokukhuphuka ngamafithi ayi-157.Wengeze ngokuthi ujantshi omncane odlula emhubheni uphephe kakhulu kunokusebenzisa ujantshi omncane phezu kwebhuloho elingamamitha angu-150 phezu kwamanzi.(Ngicabanga ukuthi ujantshi omncane kufanele ukhishwe ngokuphelele engxoxweni yezinye izinketho zeWest Seattle Bridge.)
Ngenkathi umphakathi usalinde ukuzwa ukuthi i-Seattle DOT izofuna yini eminye imikhiqizo, kuhle ukubona ukuthi umphakathi ubamba iqhaza kwezinye izindlela ezisebenzayo.Angiyena unjiniyela futhi angazi ukuthi lokhu kuzosebenza yini, kodwa isiphakamiso siyathakazelisa futhi sifanele ukucatshangelwa ngokujulile.
