Caltrans says Labor Day bridge opening not firm—bolts need tests

A month after those bad bolts were discovered on the Bay Bridge, Caltrans continues to struggle with public relations over how to deal with the mess. Until now, officials have kept up a brave front, implying that problems with one of the bridge’s key seismic safety features shouldn’t thwart the long-planned day-after-Labor Day grand opening. Now, however—weeks after the bridge woes became public—they’re saying the bolts will need to undergo two weeks of strenuous tests and that the results will determine whether the opening will be postponed.
