File talk:Abutment (PSF).jpg

No offence, but I don't think the areas indicated in this diagram are the actual abutments of the bridge. The abutments are at each end of the bridge and would usually take the form of a heavy stone or brick construction with earth piled behind it. The purpose of an abutment is to resist the outward thrust of the the arch. The items indicated in the diagram only provide vertical support. If I was asked to name them I would call them piers. 83.104.249.240 (talk) 19:49, 11 May 2009 (UTC)
