The Lansdowne Bridge Rohri was a railway bridge in present day Pakistan.
A marvel of nineteenth century engineering, the 'longest "rigid" girder bridge in the world' at that time, was begun in 1887. The Indus Valley State Railway had reached Sukkur in 1879 and the steam ferry which transported eight wagons at a time across the Indus was found to be cumbersome and time consuming. Designed by Sir Alexander Meadows Rendel, the girder work weighing a massive 3,300 tons was erected by F.E. Robertson, and Hecquet. The ferry link between Rohri and Sukkur became redundant when Lord Reay Governor of Bombay. Detutizing for Lord Lansdowne, the viceroy, inaugurated the Bridge on March 25, 1889.
