27 May 2013
One landscape colour digital photograph taken on 27 May 2013 of a retaining wall in Sumner Road which was replaced due to earthquake damage. The original wall was created using red volcanic rock. Many walls like this were built using the Hard Labour Gang from the Lyttelton Gaol. The replacement wall has a small section of stone installed to show what the wall used to look like. It is intended to reface the wall using stone salvaged from collapsed walls.

Researcher comments/remarks
Many of Lyttelton's retaining walls sustained earthquake damage and the process of rebuilding those owned by the Christchurch City Council is being managed by the Stronger Christchurch Infrastructure Rebuild Team (SCIRT). Work on the town’s retaining walls is expected to take until 2015 to complete with the replacement walls designed to withstand future earthquakes. One of the engineering features being incorporated is the use of ground anchors to tie the wall to the slope behind by drilling horizontally into the hillside then filling the hole with reinforcing and a cement grout which is then secured to the wall.
