The new wall will retain and protect the residential gardens and adjacent slopes and offer scour and erosion protection to the river banks. The works also include the installation of scour protection around the foundation of the North abutment on the footbridge. This will involve the installation of a 1m wide insitu concrete scour protection at the South, East and West face of the abutment foundation. The embankment in front of the abutment, including rock armour protection will need to be reconstructed over a length of 5m, up to 2m in height. The existing rock armour protection to the west side of the structure should be reinstated using existing materials, over a length of 5m varying height up to 2m.
