It's not just the Bay Bridge that is giving Caltrans reason to worry.

Caltrans says there are problems with seismic joints on the Carquinez Bridge.  

The newest span that 11-year old bridge on I-80, which crosses the Carquinez strait between Vallejo and Crockett, has several of seismic joints, which are supposed to absorb movement.

An engineer's reports shows at least some the joints are cracked and off-center.

Even though temporary fixes have been made, there's no word from Caltrans on a permanent solution.
