Anti-corrosive measures to protect bridge from spitting

12:05 pm on 28 November 2011

Engineers in the Indian city of Kolkata (Calcutta) are having to come up with special measures to save one of the country's most famous bridges from the effects of people spitting on it.

The BBC reports that scientists say parts of the Howrah Bridge are corroding because of the high acid content of saliva from people chewing Gutka, a mixture of betel nut and tobacco.

Engineers will place fibre coverings, containing pictures of Hindu gods and goddesses, on the bridge's hangers.
