Westway Flyover, A40, Paddington, City of Westminster, London, 17/09/1969. The transporter crane lowering a deck unit of the Westway Flyover into place as it spans Great Western Road. The transporter crane was specially designed and built by Laing's Plant Department. The four-legged gantry made 400 trips along the carriageway of Section 5, lifting the individual deck units from the Harrow Road end, transporting them the length of the highway and lowering them into position. The deck units for Section 5 weigh up to 130 tonnes and are more than 28 metres wide, carrying all six lanes of the carriageway. The units are supported on a temporary structure of steel beams weighing 160 tons until each span is complete, stressed together and self-supporting.
