Kumapeto kwa Marichi chaka chino, chifukwa cha kuchuluka kwa mapazi awiri m'milungu iwiri, akuluakulu a Seattle Department of Transportation (SDOT) adatseka magalimoto pa West Seattle Bridge.
Ngakhale akuluakulu a SDOT anayesa kulimbitsa mlathowo ndikuzindikira ngati mlathowo ungapulumutsidwe kapena ngati mlathowo uyenera kusinthidwa, adafunsa wokonza kuti athandizidwe pakusintha mlatho., Ngati tsopano tikutha kukonza kwakanthawi kochepa kuti titsegulenso mlathowo posachedwa, koma m'zaka zingapo zikubwerazi, chithandizo chokonzekera chikufunikabe kuti chilowe m'malo mwa mlathowo."Mtengo wa mgwirizanowu umachokera ku US $ 50 kufika ku US $ 150 miliyoni.
Poyambirira, New York City Qualification Requirements (RFQ) yamakampani opanga uinjiniya idawoneka kuti ili ndi njira zina zolumikizira.Komabe, pamene thandizo la anthu likuchulukirachulukira, mainjiniya opuma pantchito a Bob Ortblad adathandiziranso New York City kuphatikiza njira zina zanga mu RFQ.Mzinda wa New York wapanga zowonjezera pa pepala lofunsa mafunso, lomwe limati: "Njira zina zidzawunikidwa ngati gawo la mgwirizano, kuphatikizapo koma osati malire ndi njira zogwirizanitsa mawu."
Chosangalatsa ndichakuti asanaganize zokhala West Seattle Bridge pano, akuluakulu aku Seattle adaganizira njira zina pafupifupi 20 mu 1979, pomwe njira zina ziwiri zidachotsedwa.Atha kupezeka mu Njira Zina 12 ndi 13 mu Final Environmental Impact Statement (EIS) ya Spokane Street Corridor."Chifukwa cha kukwera mtengo, nthawi yayitali yomanga komanso kuwonongeka kwakukulu, adachotsedwa kuti asaganizidwe."
Izi sizosatsutsika, chifukwa membala wa anthu omwe adagwira nawo ntchito ku Harbor Island Machine Works adanenapo za EIS: "Anakumba ngalandeyo pansi pamtengo wokwera kwambiri, ndipo palibe amene anapereka ziwerengero.Tsopano, ndi chiwerengero chanji chomwe ndikufunsa, Kapena adayesapo?"
Njira yomiza chubu (ITT) ndiyosiyana kwambiri ndi ngalande ya SR 99.Mukamagwiritsa ntchito "Bertha" (makina otopetsa) kuti mupange ngalande ya 99, ngalandeyo yomizidwayo idaponyedwa pamalowo padoko louma, kenako kunyamulidwa ndikumizidwa pansi pamadzi omwe adayikidwa m'madzi.
Japan ili ndi ngalande 25 zomira pansi.Chitsanzo chapafupi cha ITT ndi George Massey Tunnel pansi pa Mtsinje wa Fraser ku Vancouver, British Columbia.Msewuwo unatenga zaka zopitirira pang’ono ziŵiri kumangidwa, kuphatikizapo zigawo zisanu ndi chimodzi za konkire, ndipo anaikidwa m’miyezi isanu.Ortblad amakhulupirira kuti ngalande yodutsa ku Duwamish ikhalanso njira yachangu komanso yotsika mtengo yomangira.Mwachitsanzo, adapereka 77 SR 520 pontoon yofunikira kuwoloka Nyanja ya Washington - ma pontoon awiri okha omwe adamira amatha kuwoloka Duwamish.
Ortblad amakhulupirira kuti ubwino wa tunnel pa milatho sikungochepetsa mtengo komanso kufulumizitsa ntchito yomanga, komanso moyo wautali wautumiki komanso kukana kwamphamvu kwa chivomezi.Ngakhale kusinthidwa kwa milatho pakachitika chivomezi kumakhalabe kosavuta kusungunuka kwa dothi, ngalandeyi imakhala yosalowerera ndale ndipo chifukwa chake sichikhudzidwa kwambiri ndi zivomezi zazikulu.Ortblad amakhulupiriranso kuti ngalandeyi ili ndi zabwino zake zochotsa phokoso, zowoneka bwino komanso kuwononga chilengedwe.Osakhudzidwa ndi nyengo yoipa monga chifunga, mvula, ayezi wakuda ndi mphepo.
Pali malingaliro ena okhudza malo otsetsereka kulowa ndikutuluka mumphangayo komanso momwe zimakhudzira njira yodutsa njanji yopepuka.Ortblad amakhulupirira kuti kuchepetsa 6% pazotsatira zonse ndi chifukwa kutsika mapazi 60 ndi njira yayifupi kusiyana ndi kukwera mapazi 157.Anawonjezeranso kuti njanji yopepuka yodutsa mumsewu ndi yotetezeka kwambiri kuposa kuyendetsa njanji yopepuka pa mlatho wa 150 mapazi pamwamba pa madzi.(Ndikuganiza kuti njanji yopepuka iyenera kuchotsedwa pazokambirana za njira zina za West Seattle Bridge.)
Pomwe anthu akudikirira kuti amve ngati Seattle DOT angafunefune zinthu zina, ndikwabwino kuwona kuti anthu akutenga nawo gawo pazosintha zina.Sindine mainjiniya ndipo sindikudziwa ngati izi zitha kugwira ntchito, koma lingalirolo ndi losangalatsa komanso loyenera kulingaliridwa mozama.
