Why is that the only one then? The other lanes don't have cracks. Other bridges on the 880 don't have cracks. The Bay Bridge doesn't have cracks like that.
anyway as far as I know, concreet changes sizes in heat and cold, and a crack gives space for that change and frees the structure from that kind of pressure.
Just because there is a gap in the pavement shouldn't be much reason for concern. The road surface (concrete, asphalt) won't provide any real strength in an earthquake against shearing and tensile loads. That strength will only come from the steel members which are probably only at some interval anyway. Of course, I could be making that up.
I noticed that gap back in 1999 and it hasnt changed

dude, things expand in heat, that's why they PUT the crack... - i mean, GAP, there....
have you seen some rail roads before? they all have the same.

Shouldn't be a problem but interesting to bring up either way. I don't miss oakland at all.
