A hulking 700t steel Parker truss making up Bishop's Bridge at Paddington Station, west London, was strand jacked 9m into the air in the early hours of Sunday morning. The lift was carried out during one of Network Rail's standard three hour maintenance possessions.
The truss will remain suspended from its four heavy steel lifting towers for 15 to 18 months. This will allow main contractor Hochtief and steelwork specialist Cleveland Bridge to construct a slim new 101m long steel girder bridge and slide it in from the northern abutment (NCE 19/26 August). Once the new bridge is securely in place the old truss will be lowered onto it and hauled off for demolition.
