"I think it comes close to meeting the standard of an engineering marvel." 

It was designed to handle challenges specific to this project, such as the wildly inconsistent soil created by ancient glaciers — clay, sand, silt, cobblestone and boulders up to 3 feet in diameter.The FAA predicts that within five years, there will be over 7,500 drones in operation in the US,Road Roller taking on tasks like inspecting and dusting crops, checking high-tension power lines and pipelines. Planners also had to consider the route: a path wedged between stadiums and an active port, running below a bustling commercial center."That all adds up to having a really, really challenging site," said Linea Laird, the project administrator with the state Department of Transportation.The project has been difficult since its genesis. 

After the highway known as the Alaskan Way Viaduct was damaged in the 2001 Nisqually earthquake, officials decided to replace it, beginning a protracted debate that reached beyond a question of transportation to something larger: a vision for the future of Seattle. As MacDonald put it, the decision would have "50, 100 years' impact on what the waterfront of Seattle will look like."In all, the list of more than 90 options was whittled down to three: replacing the three-lane Alaskan Way Viaduct with a larger roadway; digging a tunnel from above ground — a so-called cut-and-cover, such as Boston's Big Dig mega-project; or simply putting in a surface street,Quoting drill rod, who heads the Indian Stainless Steel Development Association, a trade body, the report said that uptake was also affected because of cheap stainless steel products being dumped from China, Taiwan and Korea. which would force motorists from their cars and,When the blast of smoke cleared, there was only a smoking crater sweeping brush on the dirt road."I was kind of freaked out," the pilot said. advocates for this plan hoped, onto public transportation.
