Boggan waxa uu sharaxayaa sifooyinka muhiimka ah ee mashruuca. Naqshadaynta la soo bandhigay waa fikrado. Naqshada-dhisuhu wuxuu dhamaystiri doonaa jadwallada iyo naqshadaha, kuwaas oo laga yaabo inay ka duwanaadaan naqshadaha fikradaha.
Horumarka Bulshada
Inta lagu jiro horumarinta mashruuca, dhismaha, iyo wixii ka dambeeya, WSDOT waxaa ka go’an badbaadada, caafimaadka, iyo tayada nolosha bulshooyinka ku dhow. Boggan waxa uu iftiiminayaa sida SR 509, 24th Avenue South to South 188th Street – New Expressway Project uu wax uga qabanayo saddex walaac oo waaweyn oo aanu ka maqalnay deriskeena: marin-u-helidda badan, badbaadada, iyo sawaxanka.
Hababka badan & badbaadada lugeeyayaasha
Dadka Washington waxay adeegsadaan habab kala duwan si ay ugu kala gudbaan meelaha. Iyadoo tan maskaxda lagu hayo, injineerada mashruucu waxay naqshadeeyeen is-weydaarsiga iyo isgoysyada gudaha SR 509 cusub ee wanaajinaya badbaadada iyo gelitaanka xubnaha bulshada ee socda, raaca kuna lugeeya.
Wadada lagu lugeeyo oo balaaran lehna xeen daab taraafikada oo ku yaal waddada kore ee South 160th Street iyo South 192nd Street buundada cusub waxay awood u siin doontaa in si badbaado leh looga gudbo SR 509. Dhanka koonfureed ee Koonfurta 188th Street, waddo kala duwan oo la isticmaalo iyo calaamad cad oo ku taal isgoysyada wareega ayaa si aan kala go’ lahayn ugu xidhi doona Harada Degmada King ilaa Sound raad-isticmaalka.
Laakiin kaliya ma dhamaystireyno SR 509. Iyada oo qayb ka ah mashruucan, WSDOT waxa ay sidoo kale bixinaysaa maalgelinta Degmada King si ay u dhisto isku xirka muhiimka ah ee maqan ee Harada ilaa Sound ee adeegsiga badan. Mashruuca 1.8-mile Harada-ilaa-Sound Trail- Qaybta C (L2ST-C) ayaa horayba u dhismay waxaana la filayaa in la dhammeeyo guga 2023. Wax badan ka baro adigoo booqanaya King County Parks’ L2ST-C bogga mashruuca .
Sawaxanka
Iyadoo la raacayo habka dib u eegista deegaanka ee 2003, isbeddelada lagu sameeyay nakhshad waddadu waxay keentay hoos u dhac weyn oo ku yimid sawaxanka la filayo inay kusoo kordhaan qoysaska, meheradaha, iyo meelaha dadweynaha ee xuduudka la leh Mashruuca Dhamaystirka SR 509. Arrinka ugu weyn ee gacan ka geysanaya dhimista qayladan ayaa ahayd kordhinta lacagta laga qaado waddada cusub ee SR 509, taasoo u oggolaatay injineerada inay dib u naqshadeeyaan waddooyin leh haadad aan badnayn gaadiidka adeegsanaya yaryahay.
Halka sawaxanka taraafikada laga yaabo inay ka sarreyso 65 decibels, WSDOT waxay dhisaysaa darbiyo cusub ee sawaxanka waxayna fidinaysaa darbiyada sawaxanka ee hadda jira. Tixraac ahaan: Talaagad gurigu waxay soo saartaa ilaa 55 decibels, halka vacuum cleaner uu soo saaro ilaa 75 decibels.
Marka lagu daro in ka badan 12,000 talaabo oo ah darbiyo cusub ee sawaxanka ah oo laga dhisay Marxaladihii 1a iyo 1b ee Mashruuca Dhamaystirka SR 509, WSDOT waxay dhisi doontaa laba darbi sawaxan oo cusub waxayna dheerayn doontaa hal darbiga sawaxanka hadda jira inta lagu jiro Heerka 2. Tan waxaa ku jira:
- Hal darbi cusub oo 874-foot ah sawaxanka yareeya oo ku yaal waqooyi-bari ee is-weydaarsiga cusub ee SR 509/South 160th Street
- Hal darbi cusub oo 1,180-foot ah oo sawaxanka yareeyo oo ku yaal koonfur-galbeed ee is-weydaarsiga cusub ee SR 509/South 160th Street
- Kordhinta 230-talaabo ee gidaarka sawaxanka ee hadda jira oo ku yaal dhinaca bari ee I-5 oo koonfur ka xigta qashin-qubka Midway.
