Building todays tunnel in one of the Country's most active seismic zone States takes a Mass of Bodies...i.e. Engineering experts, a Cal Trans Person, etc. at site. This is going to be $402 MILLION $ to be know as Calif HWY 24! Photos and news at site.

It looks like something out of a sci-fi movie! I hope it *is* as safe as the engineers say it will be. Thanks Marilyn!

" [...] Building a modern-day tunnel in one of the country’s most active seismic zones starts with a mass of bodies. A meeting to discuss the subject begins with four engineering experts, a Caltrans spokesperson, a week of data-filled emails, and a lengthy exploration of who’s missing and what they’d say if they were sitting at the same table.

But what Pat Hipley, Gursharnjeet Cheema, Ben Edalati, Sean Coughlin and Ivy Morrison say about the $402 million project that promises to erase the daily parking lot known as California’s Highway 24 with a swift-flowing commute is startlingly simple.

In an earthquake — even The Big One — the all-new fourth bore might be the safest spot in the San Francisco Bay Area. [...]"

"In an earthquake — even The Big One — the all-new fourth bore might be the safest spot in the San Francisco Bay Area." What a good read this morning.! Thanks, Marilyn for this one.

An engineer would call this a marvel, To me it looks like a foolish project but I don't have to deal with a Bay Area commute. It was horrible back in 1966!

Wow, I hope it helps with the traffic problem. Seems though whenever a project is completed the population has increased so it still is a traffic jam. I think we really need to start pushing this high speed rail and make our train and bus system more easy for people to access. Even in places that does have buses people still need cars as the buses stop running early in the evening. If one wants to take in a show or concert they can't because there is no way to come home, they might get there but can't get back.

Very interesting especially for me I'm Italian, my nation is situated all in a very seismic, where instead of the technology italians use bribes to politicians

Absolutely fascinating! What an engineering feat, the mind boggles at the challenges met and over come by these engineers and geologists.

Weren't it better if they spent the money on internal humanitarian aid? For example?

Rejee, I hope it would be a safe place since I will never forget the way the freeway pancaked on top of the one below it and so many people died in the one in 1989? Was watching the start of the World Series and will never forget what happened...felt tremors here and I live 9 hours away!

The certainly have been doing a ton of work on all of the freeways here in So. California.

This story when I saw it, was so interesting I had to share!

I lived in California for a very brief time in 1984 - experienced one earthquake in Salinas (only a 5.1), but that was enough for me ... one month later I moved back to the East Coast :)

Thank you Marilyn.
