I ka wā i hānau mua ʻia ai ʻo Barbara Walker Crossing i ka makahiki 2012, ʻo kāna hana nui ka mālama ʻana i ka poʻe holo wāwae a me nā kukini ma Portland's Wildwood Trail i ka pilikia o ka pale ʻana i ke kaʻa ma West Burnside Road.
Ua lilo ia i mea hōʻoia i ka hoʻolālā nani, hoʻohui i ka pono a me ka nani no kahi kaiāulu i waiwai (a koi) ʻelua.
Hoʻopau ʻia i ʻOkakopa 2019 a hoʻokumu ʻia i ka mahina hoʻokahi, ʻo ke alahaka he ala hele wāwae 180-kapuaʻi ka lōʻihi i hoʻolālā ʻia e hoʻohuli ʻia a hoʻolālā ʻia e hui pū me ka nahele a puni.
Ua hana ʻia ma waho o ka pūnaewele e ka Portland Supreme Steel Company i pau i kēia manawa, ʻoki ʻia i ʻekolu ʻāpana nui, a laila lawe ʻia i ke kahua.
ʻO ka hoʻokō ʻana i nā koi ʻike a me ka hoʻolālā ʻana ʻo ia ka hoʻohana ʻana i nā mea e hiki ai ke hoʻokō i nā pahuhopu kūʻokoʻa loa o ka papahana, ma ke ʻano noʻeau a me ke ʻano.
Ua ʻōlelo ʻo Ed Carpenter, he mea hoʻolālā a me ka mea pena kiʻi i ka nui o ka lehulehu, he nui kāna mau pahuhopu i ka wā i hāpai ai ʻo ia i ke alahaka.
"No ka mea, ʻo kekahi o kaʻu mau pahuhopu hoʻolālā koʻikoʻi ʻo ka hana ʻana i ke alahaka ma ke ʻano maʻalahi a me ka maopopo, pono iaʻu i nā mea ʻoi aku ka maikaʻi loa a me ka ʻōnaehana hoʻolālā maikaʻi loa e hiki ai-no laila, ʻekolu-chord trusses," wahi a Carpenter, ʻo ia hoʻi ka mea hoihoi i waho..Ke holo nei ma ka ʻōnaehana ala nui o Portland no 40 mau makahiki.
ʻO Stuart Finney, he mea hana ʻenekinia ma ke keʻena ʻenekinia ʻo KPFF ma Portland a me kahi luna papahana alahaka mua, ua ʻōlelo ʻo ia i ka hoʻopaʻa ʻana i nā ʻāpana āpau ma nā hui TYK kahi e hui ai nā paipu kākoʻo a pau paha ka paʻakikī. .
"ʻO ka mea nui, he ʻokoʻa kēlā me kēia hui," wahi a Finney, ka mea i hoʻomaʻamaʻa i ka hana no 20 mau makahiki.
ʻO ke alahaka hele wāwae ʻo Barbara Walker Crossing e pili ana i ke alanui Burnside kaʻa nui o Portland. Ua hele ola ia ma ʻOkakopa 2019.
“Pono e hoʻololi ʻia nā welds.Hiki i ka welding ke lilo i mea paʻakikī loa o ka hana ʻana.
ʻO ka inoa o Ferry, ʻo Barbara Walker (1935-2014), he kumu nui ia o ka hoʻōla ʻana o Portland no nā makahiki, a he ʻano ikaika ʻo ia o ke ʻano. Alanui a me Alahaka.
E like me kā Walker i hōʻiliʻili ai ma kahi o $500,000 mai ka lehulehu no Pioneer Courthouse Square ($15 no ka paving stone), ua hōʻiliʻili ka Portland Parks Foundation i $2.2 miliona mai kahi o 900 mau haʻawina pilikino e kōkua i ke kālā ʻana i ke alahaka.
Ua ʻōlelo ʻo Carpenter he mea paʻakikī ke hoʻohālikelike ʻana i nā leo a me nā leo he nui ma ka papahana, akā pono ia.
"Manaʻo wau ʻo ka ʻike koʻikoʻi ka hui kaiaulu nui, ka haʻaheo nui, a me ka hoʻopili nui - ke uku nei nā kānaka no ia mea," wahi a Carpenter.He hana hui nui wale nō ia.
Ua hoʻohui ʻo Finney, ʻo ia a me kāna hui, a me nā mea hana i kuleana no ka hoʻokō ʻana i nā hoʻolālā i ke ola, pono e lanakila i nā pilikia he nui i ka hoʻohālike 3D a lākou i hana ai, ma muli wale nō o nā paʻakikī o nā hui a me nā pono.
"Ke hana nei mākou me kā mākou mea kikoʻī e hōʻoia i ka laina o nā hiʻohiʻona āpau no ka mea hou, ʻaʻohe wahi no ka hewa me ka nui o kēia mau hui no ka paʻakikī o ka geometry," wahi a Finney.ʻO ka nui o nā alahaka he pololei, ʻo nā mea curved he mau pihi, a maʻalahi nā mea hana.
“Ma muli o ia mea, nui ka paʻakikī liʻiliʻi i hiki mai i ka papahana.Makemake au e ʻōlelo ʻoi aku ka paʻakikī ma mua o kahi [papahana].He nui ka hana a nā mea a pau e hoʻokō ai i kēia papahana. "
Eia nō naʻe, e like me ka Carpenter, ma waena o nā mea nui o ka paʻakikī o ke alahaka, ʻo ka mea e hāʻawi ai i ke alahaka i kona hopena holoʻokoʻa ʻo ia ka curved deck. He mea pono anei ka pilikia e hana i kēia?
"Manaʻo wau e hoʻomaka ka hoʻolālā maikaʻi me ka maʻalahi a laila neʻe i kahi mea hou aʻe," wahi a Carpenter. "Pēlā ka mea i hana ʻia ma kēia alahaka.Manaʻo wau noʻu, ʻo ka mea nui loa ka deck curved.I kēia hihia, ʻaʻohe oʻu manaʻo maikaʻi e pili ana i ka pahu lole no ka mea, ʻaʻohe a piʻo ke ala holoʻokoʻa.ʻAʻole makemake wau e huli hema ma kēlā ʻaoʻao o ke alahaka a laila huli hema ʻoi a hoʻomau.

Hiki i kekahi poʻe ke hana ma ke ʻano ʻē aʻe, akā ʻo ia kaʻu hana."
Hoʻomaikaʻi nui ʻo Carpenter i ka hui KPFF no ka hāʻawi ʻana iā ia i mea hoʻoikaika e pono ai ʻo ia e hana i nā paipu ma waho o ka papa, kahi i hāʻawi ai i ke alahaka i kahi manaʻo kūlohelohe, emergent mai ka nahele.
"He mea maikaʻi ka loaʻa ʻana o kahi mea e hāʻawi aku ai i kēia kūlanakauhale a haʻaheo iā ia, akā maikaʻi nō hoʻi e hoʻoponopono i kahi hoʻokūkū ʻenekinia maʻemaʻe," wahi a Finney.
