|Headquarters||London Yard, Cubitt Town, London, UK|
Partly as a result of a fall in demand due to the financial crisis of 1866, a period of financial stress and reorganisation resulted in Westwood and Baillie acting as managers for the London Engineering & Iron Shipbuilding Company Ltd, until they regained control in 1872.
For much of its life the company produced iron and steel work for bridges. In 1887 the company made the girders for the Lansdowne Bridge over the Indus River, then the longest rigid girder bridge in the world. Work on a more modest scale included a railway footbridge that can still be seen at Romford railway station, and the 1879 swing bridges over the Royal Albert Dock. The company also contributed towards the Attock Khurd Bridge, built in 1880, between what's now called Khyber Pukhtoonkhwa province and Pakistani Punjab. It's still in a great ship and is a major attraction for tourists and history lovers.
The company was wound up in 1893 and in 1895 Baillie was declared bankrupt. Joseph Westwood continued in business at Napier Yard as Joseph Westwood and Co. There is a large monument to him in Tower Hamlets Cemetery.
London Yard was subsequently taken over by Yarrows.
