A treat to the eyes, the cost of illuminating the bridge would be Rs 9 crore (Rs 90 million).

The height of the cable-stayed tower is equal to a 43-storey building.

The bridge would provide an additional moving outlet from the island city to the Western suburbs, thereby providing much-needed relief to the congested Mahim Causeway, which records around 1.25 lakh (125,000) public vehicles in a day.

"The eight-lane bridge will reduce the travel time between the two points from 60-90 minutes to 6-8 minutes. This will save around Rs 100 crore (Rs 1 billion) a year in vehicle operating cost alone," the official said.
