message: The Chaitainment Bridge is listed as being 17.4 trillion meters. Unless it's connecting Pluto to the sun, I think that might be incorrect. Can someone confirm this?  — Preceding unsigned comment added by 75.32.10.150 (talk) 23:47, 16 October 2011 (UTC)

message: Does the table mean list of arch bridges by length of span? I assume so, since it sure isn't by the column labeled length. If so, shouldn't the wording of the first sentence say that, instead of just list of arch bridges by length? Gzuckier 20:06, 26 April 2007 (UTC)
replies: text: I think it is explained in leading section. Span lenght is chosen as the closest to length of main arch. Leading section can be reprased to explain it better. Maybe article name can be List of largest arch bridges, but till now nobody have problem with that. --Jklamo 20:34, 26 April 2007 (UTC)

In addition to the above, the Newark Bay Bridge, with a main span of 1,270 ft, was also excluded.  —Preceding unsigned comment added by 96.250.246.19 (talk) 21:17, 26 October 2010 (UTC)
thread_title:  Missed Bridge 

message: This list is shaping up nicely.
While working on List of largest suspension bridges it became clear that there is no agreed upon way to measure the overall length of a bridge.  Some are measured from the beginning of the first span to the end of the last.  Some are from the beginning of the first ramp to the end of the last.  Some are from the beginning of the construction project to the end.  Some are from the last exit on the road before the bridge to the first one after.  Sometimes you can find out how the length was measured.  Sometimes the information is not available. This is not a problem with the lengths of spans.  
Since there is no agreed upon convention for overall length, there isn't much value in comparing all these apples and oranges (pears, strawberries, etc...) on a list.  If they remain, there should be a note of explanation, but I'd advocate removing the entire column.  I'd rather see the location of the bridge in more detail (not just the city).  -- ☑ SamuelWantman 02:20, 2 June 2007 (UTC)
replies: text: Yes, overall lenght number is sometime incomparable. I prefer explanation note than removing all column. I'd welcomed to see more detailed location than country. Maybe two more columns Crosses and City (Village) will be the best. --Jklamo 15:38, 4 June 2007 (UTC)

message: Data for Banghwa Bridge are sourced from there  (i.e. from there . If somenoe has another numbers for that bridge, show it. --Jklamo 20:10, 8 June 2007 (UTC)
replies: text: Hmm, that source  claimed that 540m is lenght of all 5 spans and that  real lenght of arch span. I will correct it. --Jklamo 20:15, 8 June 2007 (UTC)

message: Hello, the french version of this list (Liste des ponts en arc les plus longs) have been updated with many corrections and new bridges added. It was difficult to work on the Mediawiki code for this list and there was some problems with the "Rank" column so we decided to work on an excel file with a manual numbering. The transposition is very easy with the "Concatenation" function, you can put the code on the modification page with a simple copy/paste.
The XLS file is available on this page : ledefi.pagesperso-orange.fr/Ponts2.htm (see Ponts en arc les plus grands].
There is unfortunately a little problem between the english and the french version : bridges names and locations haven't the same traduction (for example, the first one Chaotianmen Bridge is translated into Pont de Chaotianmen and China is translated into Chine, otherwise we could use the same xls file for two languages.
You can read more explanations on the discussion page of french version of this list.
Also, a wikimedia category have been created with all bridges present on this list : Category:Longest arch bridges

thread_title: Yet another bridge missing

message: No one but the most technical person reading this would have any idea what "CFST" is. Articles are supposed to be written in language that the layperson can understand, avoiding technical jargon. I had to go to Google, outside Wikipedia, to find CFST stands for concrete filled steel tubular, and is a method of hardening the footings, and pillars, against earthquakes. Someone with knowledge should create on article titled, Concrete filled steel tubular. There is a "CFST" article in Wikipedia, but is is about a unit of the French Army.

message: I've removed all photos in this part for a clearer view of timeline, and the four last bridges as there's no proof of these records.
The book in citation said for Caravan Bridge that "it's the oldest in existence but this is difficult to justify", "Ponte di Nona is one of the two oldest dated Roman bridges" and nothing for Rhodes Footbridge and Arkadiko Bridge (the last one is said to be the oldest arch bridge still in existence and use, not a span record). The only first span record given is Pons Aemilius. I put these four last bridges here as long there're no better informations about them.
Just a remark, Trajan's Bridge is a wooden arch bridge who breack span record with 51 meters and 1135 meters long, for me it's strange that there're no such bridges with span between 32 and 51 meters constructed before.--Glabb (talk) 21:03, 30 January 2017 (UTC)
