An old 3,48-kilometer viaduct is blown up to be replaced in Wuhan, Central China's Hubei province, May 18, 2013. The bridge was built in 1997 and was the longest viaduct in the province. It will be replaced with a 5.1-kilometer long bridge in 2015 after dismantlement amid safety hazards and transportation demand in the city. [Photo/Asianewsphoto]
