San Francisco - Oakland Bay Bridge

keeske · October 8th, 2005, 12:16 AM

A new concrete bridge is being build from the Oakland side towards SF, to lighten the load of what is said to be the bussiest bridge in the world.

Anybody has already seen any plans for the bridge?

it's not going to lighten the load, it's going to replace it

What will it happen to the old bridge?

That is a beautiful bridge, though it would be excellent if they added some colour....

when the new bridge is fully finished the old one will be destroyed.

That's only half right. The bay bridge is actually 2 separate bridges but most people just think of it as being one bridge. There's one section that goes from Oakland to Yerba Buena Island. And the other continues from there to San Francisco. The section between San Francisco and the island will be kept. However it will be retrofitted (structurally reinforced).

but...

The section between the island and Oakland will be replaced. That's what you're seeing in the pics.

Until I saw this pic I didn't know what "self-anchoring" meant (the bridge is described as a self-anchoring suspension bridge). I see from the pic that the cables loop around under the bridge deck - so I presume that the cables themselves serve to help stabilize or "anchor" the bridge without the need for anchors in bridge abuttments like you see on other suspension bridges.

it's really going to be a wide bridge huh? since its not going to be double decker anylonger, well for the first half, that's going to be really challenging when they have to re double deck it, to attach to the second half.

Azn_chi_boi · November 12th, 2005, 12:34 PM

Why bother destroying the old one? That will cost a lot of money, just abandon the old one. Why not use both, like old one for traveling to Oakland(since its free) and new one to SF(since you need to pay toll)?

How strong can the new bridge withstand an earthqauke? How about the old one?

crazyevildude · November 12th, 2005, 02:51 PM

The old one can't withstand another earthquake without retrofitting it - hence the, building a new one. To leave it open would make the building of the new one a little pointless.

612bv3 · November 13th, 2005, 08:34 PM

They also said that retrofitting the old bridge would cost as much as building a new one.

mr_storms · November 13th, 2005, 08:54 PM

any recent photos of construction? I havent seen the construction in a while, so im interested in progres (or lack thereof

)

Its really wide(10 lanes) cause it's the busiest bridge in the US, carrying approximately 300,000 cars daily. The Golden Gate Bridge is our postcard to the world, but the Bay Bridge is the region's "Main Street."

Here are some shots from the original span's construction...

The approach ramps being built in the early 1930s..Oakland in the background. Today this spot is the most important freeway interchange in Northern California

The Western Span leading into The City

The Eastern Span as its connected to Treasure Island

The San Francisco approach

huh? re-double-deck it? they wont have to re-double-deck anything, the eastern span (the new one being built) will involve NO double-decks..... they'll build this one and demolish the old eastern span.

so as not to confuse anyone, the existing WESTERN SPAN will NOT be demolished. EASTERN will.

A good photo laying out the site and showing construction (thanks to bay_area for the great photo)

The Western span that is not being changed is on the top, while the eastern span on the bottom is
