*1872-74: First site survey is made of Rohri-Sukkur area by [[James Ramsay]] of the [[Public Works Department]] to bridge the River Indus here. He proposed a 650 feet(200M) long suspension bridge.
*1875: The survey was continued by Major General Sir James Browne who recommended a stiffened suspension bridge with cables formed of steel links and a span of 786ft(238M).
*1879: Railways reached [[Sukkur]] from [[Karachi]] and [[Guilford Lindsey Molesworth|Sir Guilford Molesworth ]] suggested a three-hinged arched bridge. [[James Richard Bell]] suggested a parallel truss cantilever bridge with a main span of 680ft(206M). These schemes were considered unsatisfactory and shelved.
*1882: A scheme of a bridge with 250ft(76M) spans supported on masonry piers was proposed. This design was almost chosen when a severe flood in the river took its bed depth down to 100 ft and this design was shelved.
