Yes. The initial design of the causeway was to put a bridge in place, but at the time the causeway was being put in, the river flow was actually quite high, and it was judged that it would be unsafe to put that bridge in, that the foundation wouldn't support a span. Because of a terrible accident, a tragedy, in fact, that had occurred previously in which we lost a life as a result of a gravel operation, it was determined that it was unsafe to construct a bridge.
The decision was made to go with the large rocks of the size that I talked about, and then subsequently the culverts were installed to further facilitate flow. Finally, a decision was made to postpone the operation altogether.
