획기적인 도로차량 통제 안전시설 장비 '지퍼트럭' The mesmerizing Golden Gate Bridge 'zipper truck' that lays out..(VIDEO)

The mesmerizing Golden Gate Bridge 'zipper truck' that lays out $30million safety barrier every day

지난 50년동안 차량 통제 안전시설은 수작업 설치에 의한 점멸관 같은 플라스틱 

튜브관들이었다.

이제 플렉시블한 재질로 만들어진 차선을 분리해주는 안전방호시설이 '지퍼트럭'에 

의해서  설치가 가능해졌다. 

마치 지퍼로 잠그듯  자동으로 방호시설들을 설치한다는 의미이다.

전 같으면 수작업으로 상당히 많은 시간과 노력이 들었지만 이번 새 안전방호벽과 

지퍼트럭으로 획기적 시간단축 등 보다 효율적인 도로의 안전통제가 가능해졌다.

새 안전방호시설은 차량의 정면충돌 사고를 감소시키기 위해 개발됐다.

80년의 역사를 간직하고 있는 금문교는 이동식 중앙분리대 설치를 위하여 지난 토요일 

52시간 동안 통행이 전면 금지됐다. 금문교 주차장도 문을 닫았다.

보행자, 자전거, 버스 등은 통행이 가능한데 현재 미 샌프란시스코 금문교의 통근차량

들의 통제를 위하여  지퍼트럭이 2.6km에 달하는 3천만불 규모의 안전방호시설을

24시간 설치작업 중으로 있다.

For 50 years, lanes were divided by lines of small plastic tubes 

Now a flexible barrier has been set up and can be moved by the vehicle

Was installed last weekend while the 1.7-mile stretch was closed to traffic

The new barrier has been set up in a bid to reduce head-on collisions  

By WILLS ROBINSON FOR DAILYMAIL.COM

For more than 50 years, a worker was forced to sit on the back of a truck and slowly drop plastic tubes to set out lanes on the Golden Gate Bridge.

Every day, their direction and positioning changes to account for commuter traffic, meaning an employee had to go through the arduous task every 24 hours. 

But a new piece of mesmerizing machinery means the traffic set up the 1.7-mile San Francisco structure can be completed in a matter of minutes.

Safety: The flexible partition that was put in during maintenance work last weekend was designed in a bid to reduce head-on collisions 

A new 'zipper truck' has been introduced. The vehicle automatically lays and moves a lane barrier as it drives over the bridge. 

Last weekend, the bridge was closed so the new safety barrier, designed to reduce the dangers of head-on crashes, could be set up.

For the longest period in its nearly 80-year history, the bridge was closed early Saturday to all but pedestrians, cyclists and buses to install the barriers on the 1.7-mile-stretch. 

A survivor of a 2008 head-on crash on the bridge spoke Sunday from her wheelchair to help inaugurate the new barrier, made of steel-clad concrete blocks that can move across the span's six lanes to accommodate traffic demands.

The zipper truck moves the barrier to another lane location. It is said to have cost around $30million 

Dr. Grace Dammann, who pushed for a safer median barrier since becoming paralyzed from the crash, said she decided to drive in the 'suicide lane' because she and her daughter were running late. Brian Clark, who was driving in the opposite direction, had just learned his father had terminal cancer.

'He passed out at the wheel, crossed over and hit my car,' Dammann recalled.

She said she and Clark became friends as they urged the district to approve the $30 million barrier.

'I am so grateful,' said Dammann, who came to the ribbon-cutting ceremony with Clark. 'Brian and I thank you.'
