One of the most unusual viaducts to be built in China, the Ganhaizi Bridge is an experimental truss bridge that uses steel tubes for nearly the entire structure. The decision to try new engineering technologies is rare in China and that makes Ganhaizi Bridge a welcome relief from the monotony of yet another H-frame ladder pier and beam style concrete bridge that is common throughout the country. But from an aesthetic viewpoint, the busy mass of horizontal and diagonal truss members is not entirely welcome.
The long curving viaduct is part of several tunnel and bridge loops that were necessary to gain elevation without incurring a steep grade on the mountainous new Yaxi expressway. The most impressive bridge along the route is the towering Labajin Bridge with a maximum pier height of 182.6 meters.
There are some sources that have a height of pier height of 107 or 117 meters for Ganhaizi Bridge. The maximum span length is 62.5 meters.
