Residents of Hong Kong react to the opening of the world's longest sea-crossing bridge. The 55-kilometer (34-mile) long bridge links Hong Kong to mainland China. The $20 billion bridge took almost a decade to build while incurring major delays and cost overruns. Rebecca Ko, a resident of Hong Kong said, “It wasted a lot of Hong Konger's money. Right? It's meaningless for normal Hong Kongers. We rarely go to the mainland China. We would hardly use the bridge.” The bridge also includes an undersea tunnel allowing ships to pass through the Pearl River delta - China's crucial manufacturing sector. Its opening will cut travel time across the delta from several hours to just 30 minutes.
