If you have the most recent version of Google Earth, you can go to the "View" menu and click "Historic Imagery" and a slider will appear allowing you to view older (and sometimes newer!) imagery of a locatin, provided satelite imagery exists.
Googgle Earth will use the clearest / sharpest image, not always the newest. The "Default" image for my neighborhood and surrounding area is 2005... but there are several newer images availble up to 2007.
My assumption that the bridge was lost was based on the fact that the aerial views on Terraserver and Google Earth did not appear to show a truss bridge. This is likely due to the color of the truss (silver instead of rust), and the fact that the bridge does not appear to be significantly narrower then the road.
I think that the Street View imagery should be the most recent, so this is an encouraging sign
Wow, thatís cool! Itís amazing what can be done with modern technology.
All we need now is to be able to hop over the side so we can see whatís underneath!
Robert, Iíve tracked down bridges before using Google earth only to get there and find out it had been replaced a year or more prior to my arrival. Iím not sure how often the images used are updated, but some areas seem to be quite old. So your assumption that the bridge may not exist could very well be true. Though, I think that being as this one shows up on Street View thereís a better chance that itís still there. Lets hope so anyway.
I have updated this bridge page based on Google Earth Street View. Being able to "drive" across this bridge via Street View was a pleasant surprise as I had assumed that this bridge was lost. Perhaps I should stop assuming!
