Four workers contracted to work on San Diego Zoo property were injured during a construction incident Thursday.
The workers were contracted with the zoo through the construction company Rudolph and Sletten Inc., but all four are "OK," according to a statement on Friday from the San Diego Zoo.
The construction company called emergency services and zoo security opened the service road to emergency vehicles, according to a statement.
Two of the injured went to Mercy Hospital and another went to UC San Diego Hospital, according to San Diego Fire-Rescue Media Services Manager Mónica Muñoz.
The incident either occurred in the African Rocks area, a new exhibit that just opened Friday at the San Diego Zoo, or around a bridge construction area at the zoo.
The mishap did not affect Saturday's grand opening of the African Rocks exhibit, which the zoo is calling their most ambitious construction project ever.
A towering waterfall nearly 70 feet tall is part of an impressive display inside the $68 million exhibit. Zoo officials say it's the most expensive and complex exhibit they've ever made.
