CROCKETT -- An expansion joint on the Carquinez Bridge has been damaged, Caltrans officials said Wednesday.
Caltrans spokesman Bob Haus said a loose pivot pin caused other pieces of the expansion joint to crack. Caltrans made the discovery during an inspection in May. A temporary support has been installed while Caltrans works on an emergency order for a permanent replacement.
The strength of the bridge has not been compromised, Haus said.
The 11-year-old western span of the bridge opened in 2003.
"It's easy to think of bridges of and overpasses as solid objects," Haus said. "Really, they are like pieces of machinery. They are complex and have moving parts, almost like car engines."
