Cracks in the existing span were discovered during an inspection. But traffic is moving again.

The San Francisco-Oakland Bay Bridge reopened about half an hour ago — a welcome development for hundreds of thousands of commuters who earlier had been warned that repairs would keep the span closed today.

But as The San Francisco Chronicle reports, California Department of Transportation Director Randell Iwasaki announced at 9:10 a.m. ET that:

"Through the night, the crews have worked nonstop — for almost 70 hours — and were able to complete repair work on the damaged eyebar beam found over the weekend. ... The bridge has been inspected, and it's safer than it was when we closed it on Friday."

KPIX has "raw video" of the first cars crossing the bridge this morning.
