Influential civil engineer Tung-Yen Lin had a different take when a panel approved the signature design favored by local pols. Lin predicted it would become "a monument to stupidity."
On Labor Day weekend, transportation officials will open the self-anchored suspension span, 24 years after a chunk of the old span collapsed during the Loma Prieta earthquake, six years after the signature span was supposed to be completed and more than $5 billion over budget.
Brown, now California's governor, will be conspicuously absent, attending his wife's family reunion in Michigan. I am sure his absence has nothing to do with the fact that the replacement span isn't open for traffic yet -- and already it needs a retrofit.
In March, 32 of 96 key galvanized steel rods cracked after they were tightened. They cannot be replaced because they've been encased in concrete for years. Engineers have come up with a plan to put steel "saddles" around the bad bolts at an expected cost of $23 million.
University of California, Berkeley structural engineering professor Abolhassan Astaneh-Asl thinks the new span is not safe. The single-anchor design is flawed, he warned, and the brittle bolts cannot withstand an earthquake.
Steve Heminger, executive director of the Metropolitan Transportation Commission, has assured me that he wouldn't approve opening the new span if he didn't think it to be safe. God help me, I believe him. When the transit wonks talk about redundancies in the system that can accommodate the saddles doing the work of the cracked rods, I want to believe.
I make the leap of faith even though I know that Heminger didn't know about the potential "brittle failure" until the rods snapped. Worse, his experts didn't see the problem coming.
I want to believe because it's too painful to think that after spending $6.4 billion and squandering 24 years, the Bay Area is going to get a shiny new toy that could fold like a cheap lawn chair during the next big temblor.
Will anyone pay for these costly, potentially fatal mistakes? "I don't know the answer to that," MTC spokesman Randy Rentschler told me. It hasn't happened yet.
