The £1.86bn Mersey Gateway Bridge opened on Saturday.
Construction took Merseylink Civil Contractors Joint Venture (MCCJV) more than three and a half years. The joint venture’s members include FCC Construcción (Spain), Kier Infrastructure and Overseas and South Korean Samsung C&T Corporation. The client was Halton Borough Council.
The Mersey Gateway Design Joint Venture comprised Cowi with Aecom, Fhecor and Eptisa, with architectural support by Dissing & Weitling. Cowi was the engineering designer while Aecom led the design of the landside works including 7km of new roads.
The six-lane cable-stayed structure is 2.24km long, with a central span of 1km and two approach viaducts. It has four spans supported by three pylons in the Mersey estuary. The 80m high central pylon is shorter than the two outer pylons, which are 110m (north pylon) and 125m (south pylon). 1,296km of cables connect these pylons to the bridge deck.
The bridge is the part of a new 9.2km road network, connecting Runcorn and Widnes.
