While the true need for the bridge is disputed, it is undeniably an extraordinary feat of engineering.Built to withstand a magnitude eight earthquake, a super typhoon, and strikes by super-sized cargo vessels, it incorporates 400,000 tons of steel -- 4.5 times the amount in San Francisco's Golden Gate Bridge.Guo says the most technically difficult aspect was the construction of a four mile (6.7 kilometer) long submerged tunnel.The tunnel is a crucial component because the Pearl River Delta is one of the busiest shipping areas in the world. According to the Hong Kong-Zhuhai-Macao Bridge Authority over 4,000 vessels -- everything from passenger ferries to container ships -- cruise its waters every day.Guo explains that the tunnel is made of 33 "elements" -- huge hollow blocks measuring 590 feet (180 meters) long, 125 feet (38 meters) wide and 37 feet (11.4 meters) high. Each element weighs 80,000 tons -- about the same as an aircraft carrier. The elements were precast on Guishan Island, near Zhuhai, and transported to the construction site by floating pontoons and tugboats. "We excavated a foundation trench in the sea bed, laid a rock bed, then immersed the elements," he says.The tunnel runs between two artificial islands, each measuring one million square feet (100,000 square meters) and situated in relatively shallow waters. Building islands from scratch didn't prove easy, either, says Xinglin. A structural frame was created using 120 giant, hollow, steel cylinders, each one 180 feet (55 meters) high (equivalent to an 18-story building) and weighing 550 tons -- about the same as an Airbus A380, the world's largest passenger jet."The steel structures were manufactured in a workshop in Shanghai and then transported to the site by ship," Guo tells CNN. The team used hydraulic hammers to drive the cylinders into the seabed, then filled the cylinders and the enclosed area with sand. 1915

Wisconsin Gov. Tony Evers released a statement in support of Biden and the DNC's decision."The upcoming Democratic convention is different than we’d imagined. A lot has changed since we set out on this journey more than a year ago now, but the one thing that hasn’t is Democrats’ commitment to putting health and safety first," said Evers. "It has never been more important for elected officials to lead by example—that’s the kind of leader Joe is, and that’s the kind of president we need. I know he will continue to have a presence in Wisconsin, virtually or otherwise, and I look forward to doing everything we can to win Wisconsin."This story was originally published by Mayra Monroy at WTMJ. 696
