One of the UK's biggest cranes is being used in a complex engineering operation taking place over several successive weekends. The 1000t crane is lifting a series of huge beams - weighing up to 230t each - into place over the M62 motorway near Ferrybridge in West Yorkshire. The beams will rest on a series of "wine glass" shaped piers some 17m high to provide a new three level interchange. The work forms part of the Highways Agency's USD$447 million project to upgrade the A1 to motorway standard between Darrington and Dishforth.
