Thank you, Mr. Chair. I am not sure what rock exactly is being referred to. Protection of the piers by installation of scour rock is a very significant aspect of the bridge. So one of the last things that we did was to actually monitor that, where that scour rock was underneath the water, and undertake some additional shaping of that to ensure that it is protecting the piers from any potential scour. There might have been some of that scour rock left over in a pile that can be there for future maintenance purposes. Thank you, Mr. Chair.
