Bandra Worli sea link, Maharastra
Features about this bridge:
The Bandra–Worli Sea Link is a 5.6 km long, 8-lane wide bridge that links Bandra in the Western Suburbs of Mumbai with Worli in South Mumbai.
Its weight is equal to the weight of 50,000 African Elephants put together.

Howrah bridge, Kolkata
Features of this bridge:
It weathers the storms of the Bay of Bengal region, carrying a daily traffic of approximately 100,000 vehicles and possibly more than 150,000 pedestrians, easily making it the busiest cantilever bridge in the world.
The Howrah Bridge is currently ranked the sixth-longest bridge of balanced cantilever bridge type in the world.
Corrosion has been caused by bird droppings and human spitting. An investigation in 2003 revealed that as a result of prolonged chemical reaction caused by continuous collection of bird excreta, several joints and parts of the bridge were damaged. As an immediate measure, the Kolkata Port Trust engaged contractors to regularly clean the bird droppings, at an annual expense of ₹500,000 (US$6,600). In 2004, KoPT spent ₹6.5 million (US$85,000) to paint the entirety of 2.2 million square meters (24 million square feet) of the bridge. Two coats of aluminum paint, with a primer of zinc chromate before that, was applied on the bridge, requiring a total of 26,500 liters of paint.
