National Grid starts Mersey embankment stabilisation

National Grid has said that work to stabilise an embankment close to the River Mersey that is threatening an electricity pylon will get underway this week.

Morgan Sindall will undertake re-profiling of the riverbank and place rock armour to a design by JBA Consulting at the Ashton on Mersey site in order to protect the 1960s pylon from further erosion.

Pylon risk

The eight month project will stabilise and protect the embankment at Ashton on Mersey

The pylon has previously been threatened by scour issues and a sheet pile cofferdam installed in the 1980s to protect the structure is now becoming unstable.

“This is a precautionary measure to protect the pylon and the line from any future problems,” said National Grid project engineer David Woodcock. “It is a complex piece of engineering that we expect will take until the end of October.”

Morgan Sindall will use the Trans Pennie Trail to gain access to the site with diversions in place for the duration of the work.
