Former Olympic individual pursuit champion Chris Boardman told the BBC the course was dangerous.
"I am past commenting - I am angry about it," he said.
"I went down and had a look at the course and saw those edges. We knew it was way past being technical; it was dangerous. The people who designed the course and said what safety features were needed had seen it as well and left it.
"We knew the descent was treacherous. I looked at that road furniture and thought, nobody can crash here and just get up. It is really bad and that is what we have seen today."
