The 6th Street Viaduct

The 6th Street Viaduct in Los Angeles has been slowly crumbling for years thanks to defects in the cement originally used to build it, and the city recently unveiled its plans for a replacement:

After a series of public meetings over the last two years, city engineers decided that replacing the bridge was the only viable option….A model of the proposed span shows two rectangular towers in the middle of the bridge, with cables down both sides.

….The cost of replacing the viaduct with the proposed structure is estimated to be about $345 million, officials said.

This is just idle musing, but I wonder why this bridge costs so much?  The original structure cost $2.3 million, which comes to about $36 million in today’s dollars.  In real terms, then, the bridge costs ten times as much today as it did in 1932.

Why?  Labor costs are proportionately higher today, of course.  The old bridge has to be built around and then demolished.  LA is built up and we can’t just build a cement factory on site, the way we did 75 years ago.  Earthquake standards and general permitting requirements are more stringent.

On the other hand, we also have 75 years of technology progression.  Labor costs may be higher, but we use less total labor and more machinery these days.  And computers help with most of the design work.

Like I said, just idle musing.  But it sure seems odd that after 75 years of fantastic technological progress, it not only costs more to build a bridge than it used to, but it costs ten times more.  That’s a lot of dough.  I just hope it’s shovel ready.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
