Another structure at the Rio Olympics has been destroyed by ocean waters just days before the start of the swimming marathons.

The large cement structure was set to be used as the diving platform for the start of both the women's swimming marathon on Monday and the men's swimming marathon on Tuesday.

According to Reuters, the structure on Copacabana Beach was swept away by waves and tides on Saturday.

Here is another view.

According to the Times of India, Olympic organizers have scheduled a meeting to figure out how to change the event to deal with the collapsed structure. Early speculation is that the races will have to find a new starting spot.

Swimmers were forced to cancel training sessions at the beach and instead trained in a pool on Saturday.

This is the second Olympic structure destroyed by ocean water.

In the days leading up to the Olympics, a ramp that was to be used in the sailing events was destroyed by 10-foot waves.
