The Mersey Gateway Project is one of the largest infrastructure initiatives in the UK and has been identified as one of the UK government's Top 40 priority projects in the National Infrastructure Plan. Mersey Gateway has also been recognised by KPMG as one of the 'Top 100 infrastructure projects around the globe'.
Overall the project includes 12 new bridges across Halton, 9.2 km of bridge and road construction with 7 new or upgraded junctions. The £1.86 billion lifetime cost includes the design, build, finance, operation and maintenance of the project through to 2044.
The new bridge
The design of the new Mersey Gateway Bridge is a cable-stayed structure with three pylons. It will be 2.3km long with a river span of 1km. The main bridge deck will be made from reinforced concrete and the spans will be supported by steel cable stays attached to pylons rising up to between 80 and 125m above the river bed.
Once open, the new bridge will carry up to six lanes of traffic and will have a speed limit of 60mph. Completion is due in autumn 2017.
