Concerned about bridge during quake
If cars and heavy trucks driving west across the upper deck of the Richmond-San Rafael Bridge can cause chunks of concrete as large as basketballs to fall on the unsuspecting eastbound motorists below, I can only imagine what a major earthquake would do to the structure. Transportation officials may claim that eroding concrete does not affect the bridge’s structural integrity; however, such unplanned, gridlock-inducing shutdowns and subsequent emergency repairs do not provide much confidence in its general safety.
