Work on the bridge started in 1863, barely five years after last Mughal emperor Bahadur Shah Zafar had been exiled to Rangoon, and finished in 1866. The bridge, consisting of 12 spans of over 200 inches each, was an engineering marvel of it&rsquos times, and cost the East India Railway Company the exact sum of Rs 16,16,335. Initially it had a single railway line, and was converted to a double line in 1913. It was reinforced in 1934 when the Northern Railways found it incapable of bearing the heavier traffic of the times. While the bridge hasn&rsquot inspired much poetry, and does not figure much in literature (not surprising given that it&rsquos bulky design is inspired by brute Industrial Revolution functionality), it has been noticed by travellers to the city. One of the earliest references to the bridge is in Lippincott&rsquos Magazine of Popular Literature and Science of 1876, where it is referred to as the &ldquogreat tubular bridge over the Jumna.&rdquo
