The "Signature Bridge" as the new landmark of New Delhi connects the city Wazirabad across the river Yamuna to the inner city. The dynamically shaped pylon consists of 2 inclined columns, which are rigidly connected to the driving lanes and bend mid-way. The upper portion of the pylon anchors the back-stay cables as well as the main-span cables, arranged in a harp like manner. The tip of the pylon is created by a 98 ft (30 m) high steel-glass structure, which can be illuminated to create a landmark visible from afar at night. A special detail of the bridge is that the self-weight of the pylon balances out the self-weight of the super structure through the eccentric location of its center of gravity with respect to the pivot point of the pylon footing. This serves well to reduce the load on the back-stay cables. The fact that the modules were bolted together on site instead of welded is an adjustment to the local method of construction.
