Im surprised at Oakland's lack of traffic. That's not how I remember it. But that stuff on 80 around Albany is about right.

So weird seeing the bay bridge approaches EMPTY. Im guessing the last picture is of Benicia-Martinez? I know it's not Carquinez because there is a newer bridge right next to it. Or is this the Richmond-San Rafael?

it looks like that's the bay bridge right after it happened. I think the steel feel close to six o'clock and that photo looks like it was taken around then.

Goodness, talk about a mess. Traffic on that bridge was bad enough before.

Those pictures of all the empty freeway lanes leading up to the bridge are just eerie. I feel bad for people who have to commute in the Bay Area. That bridge is supposed to handle 280,000 vehicles per day (roughly), and redirecting all of that is just a mess.

O, it looked like the bay bridge but I wrote that off thinking it was supposed to be empty but didn't think of that. Makes sense now.

an update

Bridge closure later likely for permanent fix

Michael Cabanatuan, Chronicle Staff Writer

Tuesday, November 3, 2009

The Bay Bridge is once again open to traffic - after six long days of emergency structural repairs and hellish commutes - but it will probably be shut down again in a few months for a permanent fix.

Richard Land, Caltrans' chief engineer, said Monday afternoon that while the repairs completed early that morning made the bridge safe for drivers, engineers were seeking "a better solution ... something more robust, better performing."

Until Monday, Caltrans officials had steadfastly defended the design of their fix, which involved taking the pressure off a cracked eyebar that was found during Labor Day weekend. That repair involved installing saddles above and below the cracked piece with four high-strength steel rods connecting them, then stressed to pull the weight away from the eyebar.

Caltrans engineers suspect that metal rubbing against metal, caused by high winds, caused two rods and a saddle to come crashing to the roadway last Tuesday. Their design to fix the problem was similar to what they had fashioned over Labor Day weekend, but they added elements to prevent the metal-on-metal contact.

"This is a temporary fix," Land said, "but a long-term solution might be needed. Right now the plan is not to keep the current strategy in place for the long term."

Caltrans engineers will analyze suggested repairs over the next couple of months in search of a strategy that will be as strong as the current fix but require less monitoring and maintenance than the repair just installed.

Instead of designing the long-term repair under time pressure, with the bridge closed and commuters fuming, Caltrans would plan the work and schedule a closure, perhaps in four to five months, Land said. The length of the closure would depend on the repair chosen. The options include replacing the eyebar, a huge undertaking that could involve replacing several eyebars, which join like a chain.

For the time being, Caltrans officials said they added a number of "enhancements" to prevent metal-on-metal contact, to prevent wind and bridge vibrations from causing the rods to move, and to prevent the pieces of the repair from falling to the bridge deck if they should fail again.

They spent much of the time adjusting the alignment and configuration of the metal pieces to assure they were not rubbing. Devices that monitor stresses and movement have been added, and Caltrans crews will check on the repairs daily for at least two weeks.

This used to be the southern terminus of I-355, until it was extended to I-80 in late 2007.

Chicago doesn't have that many expressways for a 9-10 million people metro area.

That's true, many suburban locations are quite far from expressways. I have even heard traffic in the suburbs is worse than on the Interstates around downtown.

Chicago is also an example that urban development is not necessarily spurred by freeway construction, as some critics say. Cities grow no matter what. Freeway construction may speed development up, but it will happen anyway.

Not true at all. Chicago has a TON of freeways.

No, you are wrong. Chicago is a perfect example of freeway construction spurring suburban development. The construction of I-90 and I-88 west of Chicago resulted in MASSIVE sprawl and the rapid growth of independent cities like Aurora and sleepy farm towns like Naperville into major 100,000+ population cities.

Sprawl has closely followed these two freeway routes.
