VIDEO: SEATTLE'S ONE SMART TUNNEL

Safety systems in the  tunnel will make it one of the smartest tunnels ever built

SR99

Heavy construction on Seattle's SR99 tunnel and SR 99 Alaskan Way Viaduct Replacement Program is wrapping up and WSDOT says the tunnel may be open to traffic this fall. A double-deck highway now runs end to end inside the new SR 99 tunnel. Earlier this month, contractor Seattle Tunnel Partners (STP) installed the last of the 1,152 road panels that together form the lower (northbound) roadway.

미 시애틀의 최첨단 SR99 스마트 터널

미국 시애틀의 SR99터널과 알래스카 고가교량 교체 프로젝트

SR99터널 현재까지 건설된 터널 중 가장 스마트한 첨단시설을 

갖추게 되며 올 가을에 개통될 예정으로 있다.

상하행 복층으로 설계됐으며 

이달 초 터널 시공사는 복층데크 1,152개중 마지막 판넬을 시공했다.

현재 도로 및 터널 개통을 위한 시험 운행과 안전시스템을 점검 중이다,

터널의 유지관리 시설로는

교통사고 감지시스템의 일부로 24시간 300개의 카메라와  교통안전 카메라가 

설치되어 있다.

최적 공기질 유지와 시계 확보를 위한 자동 환기시스템도 설치되어 있으며

또한 화재 시 긴급 경보및 진화를 위한 자동 스프링쿨러시설도 구비되어 있다.

Now crews are installing and testing the tunnel’s operational and safety systems. It’s a big job. Inside the tunnel there are:

More than 300 cameras to monitor traffic and security at all times as part of an incident-detection system.

Automatic ventilation systems designed to keep air quality and visibility high.

Automated sprinkler systems designed to put out a fire quickly at its source.

Together, these systems will make the SR 99 tunnel one of the "smartest" tunnels ever built. This video explains how the critical air quality and fire safety systems work together:

Thousands of components that make up the safety and operational systems will be tested at least three times – once to make sure they work, then to make sure they work as a system, then together with other systems to make sure all systems are integrated and functional. After the systems are all certified, STP will hand the tunnel over to the Washington State Department of Transportation so a different contractor can realign SR 99 and build the final ramp connections to and from the tunnel.

Finishing touches on the SR 99 tunnel will include:

95 miles of electrical wiring

21 miles of sprinkler pipes

15 miles of lights

13 miles of fiber optic cables

8 miles of linear heat detectors
