When Bay Area bridge need to be made stronger to withstand big earthquakes, drivers usually end up paying higher bridge tolls to cover the big bills.

So brace for a new study due out today to advise whether whether the Dumbarton and Antioch bridges need expensive seismic upgrades.

At 1:30 p.m. today in Oakland , the Bay Area Toll Authority board will hear the results of a two-year seismic study on the two bridges. The Loma Prieta earthquake in 1989 triggered upgrades on many bridges in the Bay Area, but it was determined at that time that the relatively new Antioch and Dumbarton bridges didn’t need them.

 Caltrans and the Bay Area Toll Authority decided a fresh look at the two bridges was warranted to consider information scientists and engineers have learned from more recent big earthquakes in this country and other nations.

The toll authority board meets at the Joseph P. Bort MetroCenter, first floor auditorium 101 8th Street. Oakland.
