Rowland Mason Ordish

Rowland Mason Ordish (11 April 1824-1886) was an English engineer. He is most noted for his design of the Albert Bridge, a crossing of the River Thames in London, completed in 1873, and for his detailed work on the single-span roof of London's St Pancras railway station.

Born in Melbourne, Derbyshire, Ordish was the son of a land agent and surveyor. In 1858 he patented a system of bridge suspension which he used in the design of bridges across several European rivers such as the Neva at St Petersburg.

His other projects included:

• Derby market hall (1866)
• Franz-Joseph Bridge over the Vltava, Prague (1868 – since demolished)
• Cavenagh Bridge, Singapore (1869)
• St Pancras Station roof (1869 – with William Henry Barlow)
• Esplanade Mansions, Mumbai, India (1871)
• dome of Royal Albert Hall, London (1871)
