Looking north toward the south side of the terminal wall, January 23, 1907. The bedrock is being excavated by the drill and blast method. However, blasting shock waves were affecting the cofferdam and reinforcements were necessary. The bedrock will be excavated to the full depth and width of the new channel before the terminal wall removal begins. (MWRD photo 3590)
