The Berkeley municipal pier is temporarily closed for repair and maintenance, since Wednesday.
Inspectors noticed structural damage with the pier prior to Fourth of July festivities.
The underside of the pier was found to have significant concrete spalling and corroded structural rebar, according to Berkeley City Manager Christine Daniel.
Fireworks still went off on the Fourth, but they were fired from a barge brought over from San Francisco.
City staff is working on figuring out possible methods to repair portions of the pier and the costs involved, Daniel said.
Fishermen and local business owners are also being impacted by the closure.
"It’s too dangerous to fish off the pier because there’s cement underneath the pier that is falling apart," Rafael Rosario told Berkeleyside. “You can see the rebar. It’s too hazardous to walk and fish.”
According to Berkeleyside, Rosario has been fishing at the Berkeley pier every day for more than ten years.
The pier will remain closed until repairs are completed.
