It is aslo on the critical path of water supply works for Beijing Olympic in 2008.
CGGC was awarded Lot 3 of Cao River, i.e. two third of total work. As the most difficult part in terms of construction, it includes 41 spans (30m for each) with total length of 1286.6 meters and design flow of 125m3/s and maxi flow of 150m3/s, which creates national records in terms of discharge capacity and single span.
