This is my second try with this title. The Censors are at it again.
I'll shorten the Post to see if I can get it in before they do it again.

I have been saying, on this Forum, that the Nuts and Bolts on the
Western section of the Bay Bridge are just as old and rusty as the Eastern section. Prepare for the New Replacement. You can't have half a new bridge and half an old bridge.

The people who speak on TV, for C. C. Meyers, do him an injustice in the way they try to cover up the Problem. The first words were,
"It's a crack with some rust starting to show". That is far from a crack, It is a real Break. There should be signs of a real big strain
somewhere else that caused that break.

Also, It is obvious that the rust was painted over. How much else is painted over on the bridge?

One Engineer [?] on TV said there was no danger as there is a 7X
redundancy built into the Problem... Well, that 7X safety factor didn't save the broken member. Of course an Engineer would try to protect the "Field".

What will the added weight and motion of all the cars going over the bridge do to it?

Welding is also a Problem.

Actually,in many cases a weld done right is stronger than the metal being welded. If a weld is not high quality then it becomes the weak link.

I don't trust the bay bridge. That damn thing should have been replaced years ago (especially since part of it collapsed in 1989). Unfortunately, this state has been in a perpetual state of disarray for the last two decades and can't seem to figure out which way is up much less build a safe bridge. Of course they've preferred to wait for some federal funds instead of taking care of their own problems. Its the american way. Let the rest of the country pay to solve your problems.

Bridges in 880 and 680 have been replaced but the richmond bridge only refurbished. The bay bridge carries probably the most traffic on a given day and is has only received band-aids.

Hi Mink,

The solution to the problem is to replace the Western Section of the Bay Bridge. It will have to be done sooner or later. Preferrably sooner. After getting a "Quick TV Peek" at the Prefab sections of the new part of the bridge, coming from China, I don't like to hear that the bridge is being built with "Welded Connections". "Hot Rivet" Connections are the Proven way to go.
I don't even trust High Tensile Bolts on a bridge of this size.

I take nothing "Away" from C.C.Meyers, as I think he does a masterful job of Improvising, but
that repair is a Bandaid on a Major Break. He was under pressure to get the bridge opened.

No offense meant.

The broken Link in the SF Bay Bridge is designed to move.
So are the many others in the bridge. Because of this, those Joints have to be lubricated. Is it possible that those fittings on
these connections are grease fittings?

Just Asking.

Why are you questioning if the fittings are greased??

He's not. He is questioning if the fittings are the type that are used to put grease into the area that requires lubrication. A grease fitting is a one way fitting that allows grease to be pumped in with some preasure and prevents it from flowing back out.
