The Lansdowne Bridge, over the Indus at Sukkur was one of the great engineering feats of the 19th century. The longest cantilever bridge ever built, it had to support the load of heavy steam locomotives. The bridge was inaugurated on March 25, 1889. The Ayub Bridge was built immediately adjacent to the bridge in 1962, to separate the road and Railway traffic. Hence the photographs of the Landsdown Bridge usually also show the Ayub Bridge.

The girder work, weighing a massive 3,300 tons, was manufactured in London by the firm of Westwood,
