SAN FRANCISCO (AP) - The California Department of Transportation says a seismic expansion joint on the westbound side of the San Francisco Bay Area’s Carquinez Bridge has premature wear.

The San Francisco Chronicle reports (https://bit.ly/1ofcPml ) that a Caltrans official explained the problem to an oversight panel Wednesday.

The $240 million steel suspension span over the Carquinez Strait was completed in 2003. Cracking on the joint started showing up two years ago, and a recent inspection found widespread problems in one spot.

The joint system expands and contracts as temperatures change and is intended to keep the bridge together during an earthquake. It was supposed to last at least two decades.
