#ashokasays Did you know 91:
If anyone mentions Kolkata, the first place that comes to the mind is Howrah Bridge. But did you know some of these?
1. Built in 1943 Howrah Bridge is a cantilever bridge that spans over the Hooghly River in West Bengal. A cantilever bridge is the one built using cantilevers, structures that project horizontally into space, supported on only one end. And this cantilever is sixth largest cantilever bridge in the world with a span of 480 meters!
2. The bridge does not have nuts and bolts and was built by riveting the whole structure.
3. It carries a daily traffic of approximately 100,000 vehicles and possibly more than 150,000 pedestrians, making it one of the busiest cantilever bridges in the world.
4. Bird droppings and human spitting cause corrosion to the bridge. The Kolkata Port Trust (KoPT ) engaged contractors to regularly clean the bird droppings, at an annual expense of Rs. 500000. The KoPT also spent Rs. 6.5 million to paint the entire bridge, which required a total of 26,500 litres of paint.
5. 26,500 tons of steel was consumed in the construction of Howrah Bridge, out of which 23,000 tons of high-tensile alloy steel, known as Tiscrom, was supplied by Tata Steel.
