The second element was the smaller bridge which involved the demolition of the existing bridge, and the reconstruction of a new, wider bridge. The foundations were 1.5 metres underwater, built using a dry sheet pile cofferdam anchored in the rock bed, and the new bridge was built as an integral bridge – meaning that the deck and the abutments were in one piece.
The third element involved the construction of two retaining walls which were 200 metres in length and six metres in height.
