Ganges River Bridge, Cawnpore
‘Ganges Railway Bridge, Cawnpore’ opened 15 Jul 1875  by the ‘Oudh and Rohilkhand Railway’ (O&RR) and constructed as a combined road/rail bridge crossing the River Ganges to bring the O&RR line from Lucknow into Cawnpore Town to connect to the ‘East Indian Railway Howrah-Delhi EIR Main Line’
Prior to this date the River Ganges was crossed at Jajmau near Cawnpore by using the ‘Bridge of Boats’ and a Ferry to carry passengers and goods across the river to Cawnpore Town. This continued until the opening of the bridge in 1875.
The structure consisted of twenty-five spans of 100 ft each(30.5mtr) and two land spans of 41 ft each(12.8mtr). The roadway is 9 ft wide(2.7mtr)and carried on the bottom flange of the main open box girders, the top carrying a single line of railway. The construction was very unusual and was undertaken from the Cawnpore end only as there were no facilities on the further bank. The method of construction is fully described in an 1872 article  .
Wikipedia records that the called the ‘Unnao-Kanpur Bridge’ and that “This bridge built by the British, is a twin bridge, i.e. it is two storied, the upper one is for vehicles and lower one is for foot walkers. But now it is open only for foot walkers and cyclists. Also two new bridges have been constructed, one for vehicles and other for railway trains”  .
