Engineering feat: The vast bridge, the largest cross-ocean bridge in the world, cost £960million and took four years to build
Chinese TV reports said the bridge passed construction appraisals on Monday and it, along with an undersea tunnel, would be opened for traffic today.
It took four years to build the bridge, which is supported by more than 5,000 pillars across the bay, and it is almost three miles longer than the previous record-holder - the Lake Pontchartrain Causeway in Louisiana
