Guiyang [China], February 24: Guizhou, the only province in China without plains, is home to over 30,000 completed and under-construction bridges. Nearly half of the world's top 100 high bridges are located here. The people of Guizhou have carved roads through mountains and built bridges over rivers, creating a vast high-speed transportation network. Tens of thousands of bridges connect Guizhou to the rest of the country and the world, allowing local products to reach markets far and wide.
