Andingmen Bridge is a roundabout interchange bridge located on the 2nd Ring Road in Beijing. It sits on the demolished Andingmen. The Andingmen Outer Street passes directly over the 2nd Ring Road.[1] It sits directly south of Anzhen Bridge (安贞桥).[1] Because the Ring Road is often a traffic bottleneck, the northern stretch between Andingmen and Xiaojie Bridge is often jammed, particularly in the lead to the turn-off for the Airport Expressway. The same goes for part of the road around the Deshengmen Bridge (德胜门桥) and all of the western side.
