Questions about construction defects and resulting safety concerns with the new span of the Bay Bridge are coming up again. 

Reportedly the new section of the Bay Bridge could collapse during a major earthquake.  

The issue is apparently with cracked welds on that section.

The Sacramento Bee quotes a Cal Berkeley engineering expert as saying the cracked welds done by a Chinese contractor are likely to fail in a major earthquake and that would compromise the entire structure which opened just last year.

While a Caltrans engineering report acknowledges welding standards were reduced to keep construction on track, the agency's director, Malcolm Dougherty, insists in a letter to a state legislative committee that the bridge is safe.
