Old Yamuna Bridge
The Old Yamuna Bridge, also known as Lohe-ka-Pul, or "bridge number 249", located in Delhi, is one of the longest and oldest bridges in India. Construction of the bridge started in 1863 and finished in 1866. It was opened for public use in 1867. It is a double-decked steel truss bridge which runs across the Yamuna river in the eastern part of Delhi. The bridge runs east-west across the Yamuna river connecting the city of Delhi to its neighborhood of Shahdara. It was constructed in 1866 by the East India Railway at a  cost of £1,616,335. It was built with a total length of 2,640 feet and consisted of 12 spans of 202.5 feet each. In the nineteenth century, two principal cities of North India, Kolkata and Delhi, were connected by railways, the bridge being the last link on this route. The bridge initially had a single line, and was later converted to a double line. There is a discrepancy about the year the second line was added; one source says that "In 1913, this was converted into a double line by adding down line girders of 12 spans of 202 feet  each and 2 end spans of 42 feet to the bridge." But another source says "It was built for a single railway line but converted into a double line in 1932 and reopened in 1934" because of increased traffic on this section. It has the capacity of serving roadways as well as railways simultaneously. The upper deck carries a two-lane railway line which connects Old Delhi railway station to Shahdra railway station, while the lower deck carries road traffic. A new long bridge is under construction adjacent to the Old Yamuna Bridge.
