The bridge opened 14 Sep 1876 as metre gauge([[Rail_gauge_#Metre_Gauge|MG]]) ‘[[Punjab Northern State Railway]]’(PNSR) connecting [[Lahore]] to [[Jhelum]]. The bridge was composed of iron trusses over many concrete piers. It has single railway bridge track and a road on one side of the track.  The PNSR with threee associated bridges, was the river first attempt of railway construction under the newly formed [[Railway_Branch_-_PWD|Public Works Department - Railway Branch]]. <br>The bridges were :-* ‘[[Alexandra Bridge]]’ over the River Chenab* ‘[[Jhelum Bridge]]’, over the River Jhelum * ‘[[Ravi Bridge]]’, over the River Ravi The bridge was built constructed by the PNSR in 1873 by accordance with Government Railway Gauge policy at the British engineer time [[William St. John GalweyRail_gauge#Gauge_Question|(''See separate page ‘Railway Gauge’ '')]] . This policy was reversed in Jan 1874 and assisted by the young engineer conversion of this section to broad gauge([[Hugh Lewin MonkRail_gauge#Broad_Gauge|BG]]) was completed.  [[Jhelum]] was then connected by the [[North Western Railway]] to other cities in the Indian empire, 1,367 miles(2190km) from [[Calcutta]], 1,413 miles(2260km) from [[Bombay]], and 849 miles(1360km) from [[Karachi]].<ref>[https://en.wikipedia.org/wiki/History_of_Jhelum #British_era Wikipedia "History of Jhelum"]; Retrieved on 23 Feb 201815 Nov 2020</ref>.  The PNSR was merged with other railways to form the ‘[[North Western Railway]]’(NWR) in 1886 ==Construction==The construction of the railway bridge on the river Jhelum commenced in 1873 by the British engineer [[William St. John Galwey]] and assisted by the young engineer [[Hugh Lewin Monk]].

There are 50 spans of 90 feet (27.4mtr) each giving forty-nine piers and two abutments. The details of the construction are fully given in the ‘Proceedings of the Institution of Civil Engineers, 1878’ <ref>[http://www.icevirtuallibrary.com/doi/abs/10.1680/imotp.1878.22418?src=recsys ‘Minutes of the Proceedings of the Institution of Civil Engineers’ Volume 54 Issue 1878, 1878, pp. 94-107"]; Retrieved on 15 Nov 2020</ref>. ==Present State==This bridge is still used by railway and road traffic.
