DR. Anatomy Where can I find photos of various bridge supports?
What do you mean? Are you speaking of the large structures that come up from the ground that hold the bridge up in the air, aka bridge piers? Or are you speaking of the small structures that the ends of the bridge sit on, aka pedestals, which accommodate any expansion between the bridge and the bridge pier? If you are looking for the piers, put "railroad bridge piers" into Google and you'll get a bunch of hits.
If you, or any of the superdetailers out there, are interested in discussion and drawings of the pedestals, I found an interesting document starting at about page 135 at the following link:

If you are looking for the supports at teh end of bridges,,,,AKA bridge abutments, do a google search for "bridge Abutments". YOu will find stuff under that as well, There I found this listing of some terminology you might find interesting:

After long and careful thought, they have convinced me. I have come to the conclusion that they are right. The aliens did it.
