Igihe Barbara Walker Crossing yatekerejwe bwa mbere mu 2012, umurimo wibanze wacyo kwari ukurinda abakerarugendo n'abiruka kuri Portland's Wildwood Trail ikibazo cyo kwirinda imodoka ku muhanda uhuza West Burnside.
Byabaye gihamya yubwubatsi bwubumenyi bwuburanga, buvanga akamaro nubwiza kumuryango wahaye agaciro (kandi usaba) byombi.
Yuzuye mu Kwakira 2019 ikanatangizwa muri uko kwezi, ikiraro ni inzira nyabagendwa ifite uburebure bwa metero 180 giteganijwe kugororwa kandi igamije guhuza ishyamba rikikije.
Yahimbwe hanze yikigo na Portland Supreme Steel Company isigaye ubu, igabanywamo ibice bitatu byingenzi, hanyuma ikamwa ikibanza.
Kuzuza ibisabwa byubatswe nubwubatsi bivuze gukoresha ibikoresho byagera kuntego zose zidasanzwe zumushinga, haba mubuhanzi ndetse no muburyo bwubaka.Ibyo bivuze gukoresha imiyoboro - muriki gihe 3.5 ″ na 5 ″ .corten (ASTM A847) ibyuma byubatswe byubatswe bigenewe ibyubaka bisaba gusudira cyangwa guhindurwa. Imiyoboro imwe nimwe iragaragara (ikindi kintu cyingenzi cya Corten) kandi bamwe basize irangi ryatsi.
Ed Carpenter, umuhanzi akaba n'umuhanzi kabuhariwe mu bikorwa rusange binini rusange, yavuze ko yari afite intego nyinshi mu mutwe igihe yatekerezaga ikiraro. Muri bo, ikiraro kigomba kwinjizwa mu rwego rw’amashyamba, kikaba ari ugukomeza ibyiyumvo n'ubunararibonye bw'inzira, kandi bigomba kuba byoroshye kandi bisobanutse neza bishoboka.
Carpenter, na we ukunda ishyaka ryo hanze, agira ati: "Kubera ko imwe mu ntego zanjye zingenzi zashushanyaga kwari ukugira ngo ikiraro cyorohewe kandi kiboneye, nari nkeneye ibikoresho byiza ndetse na sisitemu yuburyo bunoze bushoboka - bityo, imitwe itatu ya chord"..Kwirukira kuri sisitemu nini ya Portland mumyaka irenga 40. "Urashobora kuyubaka mubindi bikoresho, ariko imiyoboro yicyuma cyangwa imiyoboro ni amahitamo yumvikana.
Dufatiye ku buryo bufatika bwo kubaka, kugera kuri ibyo byose ntibyoroshye.Stuart Finney, injeniyeri w’ubwubatsi mu biro bya Portland by’ikigo cy’ubwubatsi KPFF akaba yarahoze ari umuyobozi w’umushinga w’ikiraro, yavuze ko gusudira neza ibice byose ku masangano ya TYK aho imiyoboro yose ifasha guhura ishobora kuba ari ingorabahizi. Kimwe mu bice by’ingufu zose zashyizweho kugira ngo habeho ibibazo bitandukanye by’amashanyarazi.
Finney, umaze imyaka 20. akora umwuga w'ubukorikori agira ati: "Muri rusange buri rugingo ruratandukanye." Bagombaga gukora buri rugingo rutunganijwe neza kugira ngo iyo miyoboro yose ihuze hamwe, kandi bashobore kubona gusudira bihagije mu miyoboro yose.
Ikiraro cyabanyamaguru cya Barbara Walker cyambukiranya umuhanda munini wa Portland Umuhanda wa Burnside.Yatangiye gukurikizwa mu Kwakira 2019.Shane Bliss
“Abasudira bagomba guhinduka rwose.Gusudira birashobora rwose kuba kimwe mu bice bigoye byo gukora. ”
Amazina ya Ferry, Barbara Walker (1935-2014), yabaye intandaro y’ibikorwa byo kubungabunga Portland mu myaka yashize, kandi ni imbaraga nke z’ibidukikije ubwe.Yagize uruhare rukomeye mu mishinga myinshi rusange yabereye muri Portland, harimo Parike y’ibidukikije ya Marquam, Pioneer Courthouse Square na Powell Butte Nature Park.Yanashyigikiye ubudacogora icyitwa 40-Mile Wild Loop.
Nkuko Walker yakusanyije amadorari agera ku 500.000 y’abaturage mu kibanza cy’urukiko rwa Pioneer ($ 15 ku ibuye rya kaburimbo), Fondasiyo idaharanira inyungu ya Portland Parks yakusanyije miliyoni 2.2 z’amadorali yatanzwe n’abaterankunga bagera kuri 900 kugira ngo bafashe gutera ikiraro.Umujyi wa Portland, Portland Parks & Imyidagaduro n’ibindi bigo byatanze amafaranga asigaye agera kuri miliyoni 4.
Umubaji yavuze ko guhuza amajwi n'amajwi menshi kuri uyu mushinga byagaragaye ko bitoroshye, ariko bikwiye.
Carpenter yagize ati: "Ntekereza ko uburambe bw'ingenzi ari ubufatanye bukomeye bw'abaturage, ishema ryinshi, ndetse n'ubufatanye bukomeye - abantu barabyishyura." Ntabwo ari abantu ku giti cyabo, ahubwo imijyi n'intara.Ni imbaraga zikomeye gusa. ”
Finney yongeyeho ko we n'itsinda rye, n'ababikora bashinzwe kuzana ibishushanyo mbonera mu buzima, bagombaga gutsinda imbogamizi nyinshi mu kwerekana imiterere ya 3D bakoze, bitewe gusa n'ubusobekerane bwose bw'ingingo n'ibikoresho.
Finney yagize ati: "Turimo gukorana n'abadusobanurira neza kugira ngo tumenye neza ko moderi zose zishyira ku murongo kuko na none, nta mwanya wo kwibeshya ufite byinshi muri ibyo bice kubera ko bigoye bya geometrie." "Biragoye rwose kuruta benshi.Ibiraro byinshi biragororotse, ndetse bigoramye bifite umurongo, kandi ibikoresho biroroshye.
Ati: “Kubera iyo mpamvu, hari ibintu byinshi bitoroshye biza mu mushinga.Navuga rwose ko bigoye kuruta [umushinga] usanzwe.Bisaba akazi kenshi kugira ngo buri wese agere ku mushinga. ”
Nyamara, nkuko Umubaji abivuga, mubintu by'ingenzi mu kiraro kigoye, ni iki gitanga ikiraro ingaruka zacyo muri rusange ni igorofa igoramye. Birakwiye ko ikibazo kibikora? Ahanini, yego.
Umubaji ati: "Ntekereza ko igishushanyo cyiza ubusanzwe gitangirira ku bikorwa hanyuma kigakomeza ku kindi." Nibyo rwose byabaye kuri iki kiraro.Ntekereza kuri njye, ikintu cyingenzi ni igorofa igoramye.Muriki kibazo, mubyukuri ntabwo numva meze neza kuri bombo kuko inzira yose iranyeganyega kandi irunamye.Gusa sinshaka gukora ibumoso butyaye hejuru yikiraro hanyuma nkore ibumoso butyaye kandi nkomeza.
Ikiraro cyabanyamaguru cya Barbara Walker cyarahimbwe hanze, kigabanywamo ibice bibiri byingenzi, hanyuma gikamyo kijya aho kiri ubu. Fondasiyo ya Portland Parks
“Nigute ushobora gukora igorofa igoramye?Nibyiza, biragaragara, byanze bikunze, trord eshatu ikora neza rwose kumurongo.Urabona ibyiza byimbitse-kuri-span ratio.None, niki ushobora gukora hamwe na trord eshatu kugirango ube mwiza kandi Bwiza, hanyuma ukerekeza kumashyamba muburyo butuma bisa nkaho bidashoboka ahandi?Tangira mubikorwa, hanyuma ujye kuri - ijambo ni irihe?- yerekeza ku bitekerezo.Cyangwa kuva mubikorwa kugeza mubitekerezo .Bamwe mubantu barashobora kubikora ukundi, ariko nuburyo nkora. ”
Umubaji ashimira byimazeyo abakozi ba KPFF kuba yaramuhaye imbaraga zimwe na zimwe yari akeneye kugira ngo ategure imiyoboro irenze igorofa, iha ikiraro ibyiyumvo kama, kigaragara kuva mu ishyamba.Umushinga watwaye imyaka igera kuri irindwi kuva watangira kugeza ufunguye, ariko Finney yishimiye kubona amahirwe yo kubigiramo uruhare.
Finney yagize ati: "Nibyiza kugira icyo utanga uyu mujyi kandi tukabyishimira, ariko kandi ni byiza gukemura ikibazo cyubwubatsi bwiza."
Nk’uko byatangajwe na Portland Parks Foundation, abanyamaguru bagera ku 80.000 bazajya bakoresha ikiraro cy'abanyamaguru buri mwaka, bikiza ibibazo byo kwambuka igice cy'umuhanda ubona imodoka zigera ku 20.000 ku munsi.
Uyu munsi, ikiraro gikomeje icyerekezo cya Walker cyo guhuza abatuye Portland n’abashyitsi ku bwiza bw’imiterere ikikije ibidukikije.
Walker (wavuzwe n’ikigo cy’amashyamba ku isi) yigeze kuvuga ati: “Tugomba guha abantu bo mu mijyi uburyo bwo kubona ibidukikije.” Ibyishimo kuri kamere bituruka ku kuba hanze.Ntishobora kwigishwa mubisobanuro.Iyo umuntu yiboneye ibidukikije, abantu bafite ubushake bwo kuba ibisonga by'ubutaka. ”
