Dumbarton Bridge closing for seismic work


The looming closure starts at 10 p.m. Friday, August 31. It's schedule to reopen Tuesday, September 4 at 5 a.m.

While the bridge is closed, crews will take the time to replace an expansion joint on the east side of the span with a state-of-the-art seismic joint, which can absorb and dissipate energy during an earthquake.
