Amey plc, previously known as Amey Ltd and Amey Roadstone Construction, is a United Kingdom-based infrastructure support service provider. Amey was founded by William Charles Amey in 1921. The firm grew rapidly during the Second World War via government infrastructure contracts. In 1959, it was contracted to supply gravel for the construction of the M1 motorway. During 1963, Amey was listed on the first time on the London Stock Exchange. Between 1972 and 1989, the company was owned by Consolidated Gold Fields. In 1995, Amey was refloated on the London Stock Exchange. Around this time, management decided to orientate the company towards support services delivery activities. In April 2003, Amey was acquired by the Spanish infrastructure services company Ferrovial.
