Formula
N/A
Step-by-step solution
1. Identify the key features of the Atal Bridge in Ahmedabad. 2. Recall that it is an iconic pedestrian-only footbridge featuring a steel truss design and a colorful tensile fabric roof. 3. Select Option (c) as the correct choice.
Explanation
Option C is correct because the Atal Bridge is an iconic footbridge built specifically for pedestrians and cyclists, featuring a steel superstructure (truss) and a vibrant, colorful tensile fabric roof inspired by the kite festival.
Shortcut
To easily remember the features of the Atal Bridge in Ahmedabad, use the mnemonic "PST" (Pedestrian, Steel, Tensile): - Pedestrian-only: Exclusively a footbridge over the Sabarmati River (no vehicular traffic). - Steel Truss: Superstructure constructed using an iconic steel truss design. - Tensile Fabric Roof: Covered with vibrant, colourful tensile fabric inspired by Ahmedabad's kite festival.
Common mistake
A common mistake is selecting option B by assuming the bridge carries heavy vehicular traffic like standard major river crossings. In reality, the Atal Bridge is exclusively a footbridge for pedestrians and cyclists. Another mistake is choosing option D by confusing its design with long-span suspension bridges, rather than recognizing its distinct steel truss structure and colourful tensile fabric roof.
Correct answer: C) Iconic pedestrian-only steel truss design with a colourful tensile fabric roof.
