In an engineering feat led by specialist engineering contractor, Expanded and HS2 enabling works contractor, LMJV (Laing O’Rourke and J. Murphy & Sons Joint Venture), the 2,750-tonne bridge structure was carried along the motorway on a self-propelled modular transporter.
The 448-wheel transporter took just one hour and 45 minutes to move the bridge span 150 metres, where it was affixed to a composite concrete deck to complete the overall bridge structure. Traditional construction methods would have required several weeks of lane closures on both carriageways, followed by additional weekend and overnight closures.
