The name of the bridge is Donghai Bridge. It was built in 2002 and the construction ended in 2005. The bridge took 3-3 1/12 years to build It opened on December 10, 2005. The purpose of this bridge was to connected Luchagang and Shanghai. The Bridge was built carrying trucks to the deep sea port of Yangshan. This is a cable-stay bridge. The Donghai bridge was 1.2 billion dollars. This bridge was made out of 400,000 ton of steal. There is a fancy monitoring device to make sure to sense when the bridge will fall down or has a major break. It was called: PXI-4472B, PXI-6652, LabVIEW, NI Advanced Signal Processing Toolkit, PXI-6602, PXI-8187 Some of the challenges is when there is a strong wind and because of the high winds. It was very hard to build the bridge because they had to build over water. They had to build under the sand and to the clay and it is softer then most. It was 32.5 kilometers (106,627.297 feet) long and the span was 6 lanes. The bridge was the first bridge to go over the water and was the longest until the Hangzhou Bay Bridge was built.
