HistoryAlfred McAlpine was a British construction firm. It was a major road builder, and constructed over 10% of Britain's motorways, including the M6 Toll (as part of the CAMBBA consortium). It is now owned by Carillion plc. The company was established in 1935 by Alfred McAlpine, one of the sons of 'Concrete' Robert McAlpine. It was based in the North West of England and specialised in civil engineering. In 1983, it ceased to limit its operations to the North West, West Midlands and North Wales and moved into other parts of the country. In 2001, it sold its house building operations to George Wimpey and in February 2008 it was acquired by Carillion plc. |
