in which cables are in a combination of radial and semi-harp arrangement; cables are spaced apart on the pylon, like the harp design, but connected to one point or a number of closely spaced points on the deck. 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 and the self-weight of the pylon balances out the self-weight of the superstructure through the eccentric location of its center of gravity with respect to the pivot point of the pylon footing, reducing the load on back-stay cables which are fewer in number converged from the main-span cables. The bridge is 675 meters long and 35.2 meters wide. Built on the Yamuna river, this bridge connects east Delhi to Wazirabad. Tourists can be transported to the top of the main pillar, which is 154 m high, from where distant views of North Delhi can be seen. * Structural Design Firm: Schlaich Bergermann Partner * Contractor: Joint venture of
