NEW: China officially opens the world’s tallest bridge, completing the project in under 4 years. The bridge features a restaurant at the top, a whopping 2600 ft above the river. The bridge not only cuts a 2-hour drive to 2 minutes, but also features as a theme park with a glass skywalk, a high-speed glass elevator, and a waterfall off the edge of the bridge. Visitors can also bungee jump off of it. The Huajiang Grand Canyon Bridge is 2050 feet above the river and spans 4600 feet over the river.
