Ewa Bauer had made the trip across the Golden Gate Bridge countless times. Still, January 12 was a special day. Over the weekend workers installed the San Francisco, California,[url=http://maintenancemachineprice@#$%&//road-maintenance-machinery/acrylic-polymer-driveway-sealers.html]acrylic polymer driveway sealers[/url]
bridge’s moveable barriers. As the chief engineer for the Golden Gate Bridge Highway and Transportation District, Bauer’s fingerprints were all over the project.The installation had gone better than she could have hoped – it had been completed eight hours ahead of schedule – but that was a short-term victory. The real test, the one with lasting impact, would be the bridge crossing. Her anxiety vanished as she started to cross. And it lessened every second of the drive. The barriers were a success. They were a natural fit. She knew it immediately.
“I could not imagine, as I drove, that those little pylons had ever been used,” Bauer said. “It seemed like the barriers had always been there. They fit.” Other commuters shared similar experiences: They felt the barriers were natural additions and asked, “Why didn’t we do this earlier?”Transportation experts say the Road Zipper System is officially coming of age, and the Golden Gate Bridge project is just the most recent example.The uses are growing,[url=http://maintenancemachineprice@#$%&//road-maintenance-machinery/glass-tube-cutting-machine-manufacturers.html]glass tube cutting machine manufacturers[/url]
too. What started as a tool to make bridges safer has evolved into a traffic management system to relieve rush-hour congestion.
Then there is the newest development: Transportation planners are using the barriers to dramatically reduce the scope of road projects – and to save hundreds of millions of dollars.“Acceptance and utilisation are increasing,” said Martin Leak, a consultant and expert on transportation systems,[url=http://maintenancemachineprice@#$%&//crack-repair/road-construction-equipment-pdf.html]road construction equipment pdf[/url]
including the moveable barriers. “I think a transformation is under way. There are lots of areas where you can’t build your way out of problems. The Road Zipper System is a solution – often the only solution.”
