GUIYANG, April 15 (Xinhua) -- Bridges are an unmistakable feature of the transportation infrastructure in Guizhou. With 92.5 percent of its area covered by mountains and hills, the province has built nearly 30,000 bridges since the late 1970s and is now home to nearly half of the 100 tallest bridges in the world.

Thanks to the construction of bridges, the mountainous province is becoming deeply integrated with the nation's transportation network, bringing an improved quality of life for local residents.
