Bidston Moss Viaduct has been formally handed back to its owners following Costain’s completion of strengthening and refurbishment work.
The project entailed strengthening 3km of box girder structure dating back to 1969. It required 1.25 million man hours of work, which was achieved without a single lost time accident.
The 730m Bidston Moss Viaduct is located on the Wirral in north west England and carries the M53 motorway over local roads and a railway towards the Kingsway Tunnel and Liverpool. More than 50,000 vehicles use the viaduct on a daily basis, including 3,000 heavy goods vehicles.
Weight restrictions were imposed on the viaduct in 2005 as a safety precaution and strengthening work began in April 2010. The scheme was funded by the Highways Agency, the Department for Transport, Wirral Council and Merseyside Integrated Transport Authority. The refurbished bridge was formally handed back to its three owners defect free on 28 March.
