Ubwo Barbara Walker Crossing yashingwaga bwa mbere mu 2012, inshingano yayo y'ibanze kwari ukurinda abanyamaguru n'abiruka kuri Wildwood Trail ya Portland kwirinda urujya n'uruza rw'imodoka mu muhanda wa West Burnside.
Byabaye igihamya cy’ubwubatsi bushingiye ku miterere y’ubwiza, bivanga akamaro n’ubwiza ku muryango wahaga agaciro (kandi ugasaba) byombi.
Iki kiraro cyubatswe mu Ukwakira 2019 kandi cyafunguwe muri uko kwezi, ni inzira y'abanyamaguru ifite uburebure bwa metero 180, iteganyijwe kugororwa no guhuzwa n'ishyamba rigikikije.
Yakozwe hanze y’aho yari iherereye n’ikigo cy’ibyuma cya Portland Supreme Steel Company, icibwamo ibice bitatu by’ingenzi, hanyuma ijyanwa mu modoka.
Guhuza ibisabwa mu buryo bw'amashusho n'ubwubatsi byasobanuraga gukoresha ibikoresho byagera ku ntego zose zidasanzwe z'umushinga, haba mu buhanzi no mu miterere. Ibi bivuze gukoresha imiyoboro - muri iki gihe imiyoboro y'icyuma ya 3.5″ na 5″ (ASTM A847) yagenewe inyubako zisaba guhuza cyangwa gupfunyika. Hari imiyoboro igaragara (ikindi kintu cy'ingenzi cya Corten) naho imwe irangi ry'icyatsi kibisi kugira ngo ihuze n'ishyamba.
Ed Carpenter, umuhanga mu by'ubugeni akaba n'umunyabugeni wihariye mu kubaka ahantu hanini hahurira abantu benshi, yavuze ko yari afite intego nyinshi mu bitekerezo bye ubwo yatekerezaga iki kiraro. Muri zo, iki kiraro kigomba guhuzwa n'imiterere y'ishyamba, ari na byo bikomeza ibyiyumvo n'uburambe bw'inzira, kandi kigomba kuba cyoroshye kandi gisobanutse uko bishoboka kose.
“Kubera ko imwe mu ntego zanjye z’ingenzi zo gushushanya yari ugutuma ikiraro cyoroha kandi kibonerana, nari nkeneye ibikoresho byiza cyane ndetse n’uburyo bwo kubaka bunoze cyane—bityo, imigozi itatu,” uyu ni Carpenter, akaba n’umukunzi wo hanze. Namaze imyaka irenga 40 nkora ku nzira nini ya Portland.” Ushobora kuyubaka ukoresheje ibindi bikoresho, ariko imiyoboro y’icyuma cyangwa imiyoboro ni amahitamo yumvikana.
Mu buryo bufatika bwo kubaka, kugera kuri ibi byose ntibyoroshye. Stuart Finney, injeniyeri w’ubwubatsi mu biro bya sosiyete y’ubwubatsi ya KPFF yo mu mujyi wa Portland akaba n’uwahoze ari umuyobozi w’umushinga w’ikiraro, yavuze ko gusudira neza ibice byose ku ihuriro rya TYK aho imiyoboro yose ishyigikira ihurira ari byo byari bigoye cyane. Kimwe mu bintu byose byakozwe mu bikorwa byose. By’umwihariko, inguni zose zitandukanye zikenewe ku bwoko butandukanye bw’ubusudi, nko gusudira no gufunga, byateje imbogamizi zikomeye ku itsinda ry’ubwubatsi.
Finney, umaze imyaka 20 akora ubu bukorikori, agira ati: “Mu by’ukuri buri ngingo iratandukanye.” Bagombaga gukora buri ngingo neza kugira ngo iyi miyoboro yose ihuzwe hamwe ku gice kimwe, kandi bashobore kubona ubushuhe buhagije ku miyoboro yose.
Ikiraro cy'abanyamaguru cya Barbara Walker Crossing giherereye mu muhanda wa Burnside unyuramo abantu benshi muri Portland. Cyatangiye gukoreshwa mu Ukwakira 2019. Shane Bliss
"Ubusudi bugomba guhinduka burundu. Ubusudi bushobora kuba kimwe mu bice bigoye cyane mu nganda."
Izina rya Ferry, Barbara Walker (1935-2014), amaze imyaka myinshi ari inkingi ikomeye mu bikorwa byo kubungabunga ibidukikije bya Portland, kandi na we ubwe ni imbaraga z’ibidukikije. Yagize uruhare runini mu mishinga myinshi ya leta muri Portland, harimo Marquam Nature Park, Pioneer Courthouse Square na Powell Butte Nature Park. Yanashyigikiye byimazeyo icyaje kwitwa 40-Mile Loop, cyarimo Wildwood Trail na Bridge.
Nkuko Walker yakusanyije amadorari agera ku 500.000 yavuye mu baturage kuri Pioneer Courthouse Square (amadorari 15 kuri buri ibuye rinini), umuryango udaharanira inyungu wa Portland Parks Foundation wakusanyije miliyoni 2.2 z'amadorari mu mpano zigera kuri 900 z'abantu ku giti cyabo zo gufasha mu gutera inkunga ikiraro. Umujyi wa Portland, Portland Parks & Recreation n'indi miryango byatanze andi mafaranga agera kuri miliyoni 4 z'amadorari.
Carpenter yavuze ko guhuza amajwi menshi n'amajwi menshi kuri uyu mushinga byari bigoye, ariko byari bikwiye.
“Ndatekereza ko ikintu cy’ingenzi cyane ari ubufatanye bukomeye n’abaturage, ishema rikomeye, n’ubufatanye bukomeye — abantu bari kubishyura,” Carpenter yagize ati. “Si abantu ku giti cyabo gusa, ahubwo ni imijyi n’uturere. Ni imbaraga zikomeye zihuriweho.”
Finney yongeyeho ko we n'ikipe ye, hamwe n'abakora ibikoresho bashinzwe gushyira mu bikorwa ibyo bikoresho, bagombaga gutsinda imbogamizi nyinshi mu bijyanye no gukora ibishushanyo bya 3D bakoze, bitewe gusa n'ubuhanga bwinshi bw'ingingo n'ibizihuza.
Finney yagize ati: “Turi gukorana n’abakora ibikoresho byacu kugira ngo turebe ko imiterere yose igenda neza kuko nanone, nta mwanya wo gukora amakosa kuri izi ngingo nyinshi bitewe n’uburyo ziteye.” Biragoye cyane kurusha izindi. Ibiraro byinshi biragororotse, ndetse n’ibigoramye bifite imigozi, kandi ibikoresho biroroshye cyane.
“Kubera iyo mpamvu, hari ibintu byinshi bigoye bigaragara muri uyu mushinga. Navuga ko bigoye cyane kurusha [umushinga] usanzwe. Bisaba akazi kenshi kugira ngo buri wese agere ku ntego ze.”
Ariko, nk'uko Carpenter abivuga, mu bintu by'ingenzi bigize ubukana bw'ikiraro, ikintu gituma ikiraro kibaho muri rusange ni urwego rwometseho. Ese birakwiye kugorwa no kubikora? Ahanini, yego.
“Ndatekereza ko igishushanyo mbonera cyiza gikunze gutangirira ku ngiro hanyuma kigakomereza ku kindi,” Carpenter yagize ati. “Nibyo koko byabaye kuri iki kiraro. Ntekereza ko ikintu cy’ingenzi kuri njye ari intebe ifite imiterere igoramye. Muri iki gihe, numva ntashimishijwe n’akabari k’ibiryo kuko inzira yose irahindagurika cyane kandi iragoramye. Sinshaka guhindukira ibumoso cyane unyuze ku kiraro hanyuma ngahindukira ibumoso cyane ngakomeza urugendo.
Ikiraro cy'abanyamaguru cya Barbara Walker Crossing cyakozwe hanze y'aho cyabereye, gicibwamo ibice bibiri by'ingenzi, hanyuma gitwarwa n'amakamyo kugeza aho kiri ubu. Portland Parks Foundation
“Ni gute ukora intebe igose? Birumvikana ko inkingi y’amashusho atatu ikora neza cyane ku murongo umwe. Ubona ikigereranyo cyiza cyane cy’ubujyakuzimu n’ubugari. None se, wakora iki n’inkingi y’amashusho atatu kugira ngo ibe nziza kandi nziza, kandi ukavuga ishyamba mu buryo butuma risa n’aho ridashobora kuba ahandi hantu? Tangira ukoresheje uburyo bwo gukora ibintu, hanyuma werekeze kuri — ijambo ni irihe? — werekeze ku byo gutekereza. Cyangwa kuva ku buryo bwo gukora ibintu ukajya ku byo gutekereza. Hari abantu bashobora kubikora mu buryo bunyuranye, ariko ni ko nkora.”
Umufundi w’ibiti ashimira cyane itsinda rya KPFF ku bw’imbaraga yari akeneye zo gushushanya imiyoboro irenga umugozi, ibyo bikaba byaratumye ikiraro kigaragara nk’ikinyabuzima kandi gishya mu ishyamba. Uyu mushinga wamaze imyaka irindwi kuva utangiye kugeza ufunguwe, ariko Finney yishimiye kugira amahirwe yo kuwugiramo uruhare.
Finney yagize ati: “Ni byiza kugira icyo utanga muri uyu mujyi no kuwishimira, ariko nanone ni byiza guhangana n’ikibazo cy’ubuhanga gishimishije.”
Nk’uko bivugwa n’Ikigo cya Portland Parks Foundation, abanyamaguru bagera ku 80.000 bazajya bakoresha iki kiraro cy’abanyamaguru buri mwaka, bikaba birinda ingorane zo kwambuka igice cy’umuhanda kijyamo imodoka zigera ku 20.000 ku munsi.
Uyu munsi, iki kiraro gikomeza icyerekezo cya Walker cyo guhuza abaturage ba Portland n'abashyitsi n'ubwiza bw'ahantu nyaburanga hakikije.
“Tugomba guha abaturage bo mu mijyi amahirwe yo kubona ibidukikije,” Walker (wavuzwe n’Ikigo cy’Amashyamba ku Isi) yigeze kuvuga. “Ibyishimo ku bidukikije bituruka ku kuba hanze. Ntibishobora kwigwa mu buryo bufatika. Iyo abantu biboneye ibidukikije ubwabo, baba bafite icyifuzo cyo kuba abacunga ubutaka.”
