Major Step For The Mersey Gateway Project
A massive concrete pour took place in the Mersey estuary during August 2015 as construction crews build the south pylon foundations for the Mersey Gateway Bridge.
It is the project's biggest single concrete pour and will involve pumping around 1,400 cubic metres of concrete into the south cofferdam to form the base of the south pylon.
The work took an estimated 30 hours to complete, with enough concrete being used to fill more than 200 trucks.
The concrete pours marked a major step in the building of the three giant pylons that will support the Mersey Gateway Bridge.
The north pylon foundations were completed at the end of July when some 1,200 cubic metres of concrete were pumped into the north cofferdam. The concrete pour for the central cofferdam foundations is next.
The three pylon foundations will sit below the riverbed and will each measure 4.5 metres high and up to 22 metres in diameter.
