Olympic swim venue may not be ready

Rio de Janeiro — Officials are preparing a Plan B in case the main swimming venue for the Rio de Janeiro Olympics is not ready for a test event in April.

Cornel Marculescu, the executive director of FINA, tells The Associated Press, "there are still a lot of things to do." He says the April 15-20 event could be moved to the nearby diving venue, which also contains a 50-meter pool.

Marculescu says the main issue is installing a ventilation system for the pool deck. He said the pool would be ready when the Olympics open on Aug. 5.

South America's first Olympics have been plagued with many problems including deep budget cuts, severe water pollution and now the Zika virus. However, construction delays have seldom been an issue.
