The Lupu bridge was officially opened in June 2003 at a total cost of $302 Million US. On completion the Lupu Bridge was the largest spanning arch bridge in the world with a main span of 550m overtaking the New River Gorge Bridge in the United States by 32m. This record is set to be broken in 2008 by the under construction Chaotianmen Bridge in China by only 2m. The total length of the bridge is 3,900m including the approach bridges on either side of the river. The bridge was originally heavily criticised as it was seen as wasteful by many people in respect to the type of bridge that was actually needed for the project.
Equal spacing of the main cables enhances the well ordered nature of the bridge and this is mirrored in the supporting columns of the approach bridges although, due to the large number of columns, at oblique angles it can look confused and overcrowded. The function and structure of the Lupu Bridge are portrayed in an obvious and simple way with subtle refinements and complexities to add to the bridge’s aesthetic appeal. Under Leonhardt’s rules, the Lupu Bridge has many of the attributes that could make it beautiful. Bridge aesthetics are however a matter of personal opinion and what may be beautiful to one person may not necessarily be so to another.
