Talk:List of largest suspension bridges

From Wikipedia, the free encyclopedia

List of largest suspension bridges is a featured list, which means it has been identified as one of the best lists produced by the Wikipedia community. If you see a way this page can be updated or improved without compromising previous work, feel free to contribute.

Basic guidelines for editing

This list took a good deal of effort by many people to reach its current form. If you would like to make changes to this article, please follow the guidelines below. Thanks for your help. 1) Verify the information is correct. If a bridge is added to the end of the list because it has a short main span you must be resonably certain that there are no missing bridges between the previous last entry and the new entry. This typically means that you have a source that lists and ranks all suspension bridges in the world. If the length of the bridge's main span puts it in the middle of the list, this is not a concern. 2) Any bridge added to the main section MUST be completed and opened for vehicular or train traffic. Bridges that are proposed or under construction can be listed in the end section. Feel free to start a new section of bridges that have been destroyed or otherwise no longer in use. 3) The locations of bridges should only be wikilinked the first time they appear on this list. This shows that the bridge is the largest in the linked location. 4) Pictures should be tagged according to Wikipedia's image use policy. If there is no such picture available, you can create a link to an external picture. 5) The rankings are also citations. Any bridge added must have a citation. The best citation is the bridge's own homepage. If there is no such site in English, the next best citation would be a source listed in the reference section. If you add a new citation source other than a bridge's homepage, please add it to the reference section 6) Please discuss page moves in advance.

[edit] Izmit Bay Bridge

I have not been able to confirm that this bridge exists. I've found citations that say it is being planned, under construction, bankrupt, or completed in 2002 or 2004. I'm guessing that since there are no news stories about its opening, that it hasn't been completed. Also, I have found no trace of it using satellite photos. The photos are probably old, but I can't even find evidence of foundation work.

This is the removed entry, in case it gets finished...

[edit] Longest does not mean Largest

This page should be renamed. Largest would be measured in volume or weight.

This is, I believe, the most common way to refer to the measure of suspension bridges. I just checked, and there were about twice as many hits at google for "largest suspension bridge" than "longest suspension bridge". The length of a suspension bridge is usually taken to mean either the length of total suspension, the length from anchorage to anchorage, the length from shore to shore, etc... This varies quite a bit, and does not really compare the size of the bridge. The larger the span, the bigger the cables, the higher and more massive the towers, the engineering sophistication, etc... I don't think the page should be renamed, and it should definately not be renamed "List of longest suspension bridges". It could possible be called "List of largest suspension bridges by length of main span". But I don't think that would be an improvement or necessary. -- Samuel Wantman 05:30, 14 Jun 2005 (UTC)

This page should be renamed, with this original page as a redirect. Unless someone also wants to list the largest ( in terms of numbers of lanes of road & rail traffic perhaps )

Actually, I think it would be a good thing to have the largest by other measures, but not rename this page. We could add largest suspension between anchorages (Akashi-Kaikyo Bridge), largest by number of lanes (I'm guessing the George Washington Bridge with 14), largest span carrying rail and roads (Tsing Ma Bridge), Longest suspension bridge structure between first anchorage and last anchorage (The three Kurushima-Kaikyo Suspension Bridges), Longest from end to end as part of a multiple bridge structure (Great Seto Bridge), overall length two tower with approaches (I'm guessing the Mackinac Bridge), double layer suspension bridge structure (Great Seto Bridge), longest road and rail suspension bridge structure (Great Seto Bridge), widest (Tsing Ma?), Tallest towers (?), etc... If someone wants to fully research this and add it to the article, please do. If not, I'll try to get to it after completing the main list more thoroughly. I think the top one to five bridges in each category would be sufficient. -- Samuel Wantman 07:27, 10 August 2005 (UTC)

[edit] Missing external links

Many bridges do not yet have an external link to their home page. They are marked with a red asterisk. If you click on the link you will end up here. -- Samuel Wantman 03:07, 13 July 2005 (UTC)

Why not just not put in the link at all, until there actually is a link to put in, rather than creating a seperate page with a custom created error message? EvilPhoenix talk 09:11, July 14, 2005 (UTC)

The numbered links also serve as the auto-numbered ranking of the bridges. Before this week we were using [http://] to serve as a missing link. For some reason, that stopped appearing as a link. Please see the discussion here. -- Samuel Wantman 09:46, 14 July 2005 (UTC)

Why not just use the # function, list each bridge with its corresponding ranking, without the ranking having to be a link. Then you could put in the link seperately. Ie:

1. Tallest Bridge
2. Next Tallest Bridge
3. Tallest Bridge after that

etc. EvilPhoenix talk 16:08, July 14, 2005 (UTC)

Sorry, I do not know how to get auto-numbering to work in a table. I tried, and the # function did not work with a table. Do you know a way to get it work? -- Samuel Wantman 21:44, 14 July 2005 (UTC)

Hmm. Good question. I don't know if that's doable or not. EvilPhoenix talk 04:29, July 15, 2005 (UTC)

More discussion about this now obsolete method of creating an error message is here. -- Samuel Wantman 07:17, 1 April 2006 (UTC)

[edit] Tokyo Harbor Bridge

I'm doubtful that the Tokyo Harbor Bridge actually exists. This was on a list of bridges that I used as a source for this list, but I cannot find any information about it. It does not appear at structurae.de. I cannot find any bridge that big in the satellite maps of Tokyo other than the Rainbow Bridge. I think it was a duplication of the Rainbow Bridge that made it on the list twice. Here is the information I removed: |- | || [2] * || Tokyo Harbor Bridge || Tokyo, Japan || 540 || 1994

[edit] Fixed links across elsewhere?

Can anyone add more info on the possible plans of contructing a tunnel and/or bridge across to the other side elsewhere? I am quite curious as to whether any steps have been taken to decide to build infrastructure links across the:

• Strait of Messina
• Fehmarn Belt
• Cook Strait
• Palk Strait
• Strait of Tartary
• Irish Sea
• Strait of Bonifacio
• Surigao and San Bernardino Straits
• Hainan Strait
• Strait of Georgia
• Kvarken
• Chacao Channel
• Strait of Magellan
• Bering Strait

Anyone with inside knowledge on any of these? I've posted similar requests elsewhere. Gruesome Twosome! 8v] //Big Adamsky 09:59, 13 January 2006 (UTC)

[edit] Additional data

Would't it be nice with info on the total lenght, hight and clearance of the bridges? Not for rating, but as additional data. I know it is difficult to define total length. Maby the width of the strait that is crossed? Zarniwoot 21:16, 7 March 2006 (UTC)

The problem with adding this information is where to put it. Adding additional columns makes the page fairly cluttered. I have considered using rollover notes to add more information they look like this . You could add information to the rollover, but the info doesn't stay on the screen long, and you have to move to each one to see the info. Here's an example: . You can also just click on the name of each bridge and go to its article, where all this information can be found. -- Samuel Wantman 07:51, 8 March 2006 (UTC)

Ok, that's a fair argument. I was thinking it would be illustrative to see the correlation of the span and the hight. But as you say, there is always the link to the bridges. I'm not sure people will notice the rollover notes. It took me a while (But maybe that's just me...). Zarniwoot 13:42, 8 March 2006 (UTC)

[edit] removed bridges

|- | || [3] * || Gran'Mere Bridge || Quebec City, Canada || 289 || 1929

|- | || [4] * || Cauca River Bridge || Colombia || 287 || 1894

|- | || [5] * || Peace River Bridge || Alberta - Saskatchewan, Canada || 284 || 1950

were removed from the bottom of the bridge. If they ever become articles, I'll return them to the list. --Samuel Wantman 07:48, 21 March 2006 (UTC)

[edit] Ogdensburg

There are two bridges in this list near Ogdensburg, New York. Seaway Skyway and St. Lawrence Bridge are both listed (with different stats). I enquired on Talk:Ogdensburg, New York and was advised that there is definitely only one bridge, and it is most commonly known as Ogdensburg-Prescott International Bridge. --Scott Davis ^Talk 23:28, 30 March 2006 (UTC)

I have fixed this and there is just one entry now. -- Samuel Wantman 09:06, 31 March 2006 (UTC)

Thankyou. I'm fixing the links and expanding the article a bit. Unfortunately, I have no photos. --Scott Davis ^Talk 10:38, 31 March 2006 (UTC)

[edit] Mackay Bridge/Macdonald Bridge?

These two bridges have different length numbers here and in their articles. 24.224.158.166 18:19, 1 July 2006 (UTC)

The numbers here are correct. The numbers on the articles came from the website for the bridge which lists the total length of the suspended spans not the length of the largest span. When I get a chance, I'll double-check structurae.de and update the articles. Thanks for spotting this. -- Samuel Wantman 19:41, 1 July 2006 (UTC)

[edit] Third Kurushima-Kaikyo Bridge

The image use for this span and Second Kurushima-Kaikyo Bridge are the same image. Also the copyright on this image is unclear, it cannot be presumed to be GFDL either it is or isnt. That if an image appears on another language wikipedia ask for the image to but added to Commons so that it can be used here. Gnangarra 10:13, 20 July 2006 (UTC)

The same image is used for two bridges becasue both spans are in the image. I have tried getting a Japanese speaker to communicate with the uploader of the image without success. I assumed GFDL, because of the poor quality of the image, which looks like it was taken from a cell phone. If someone wanted to steal an image, there are many better images to be found on the web. I don't spend much time policing pictures. If you determine that the picture needs to be deleted, so be it. -- Samuel Wantman 10:37, 20 July 2006 (UTC)

I have left a message on the Wikiproject Japan requesting help, they have been helpful before with other articles suggest you add this to your watchlist for the reply. Wikipedia_talk:WikiProject_Japan#Translation_help_please.. Gnangarra 12:05, 20 July 2006 (UTC)

The image has since been replaced with a GFDL image that shows all three bridges. I don't know which is which from the picture. -- Samuel Wantman 06:29, 7 September 2006 (UTC)

[edit] Severn Bridge

Surely this would count as the third largest suspension bridge? Does the Second Severn crossing count as well? Simply south 15:15, 11 October 2006 (UTC)

The Severn is on the list at position 20. It was never the #3 bridge. It may have been the #3 bridge in Europe when it was built. The Second Severn Crossing is a cable-stayed bridge which are not included in this list. See List of largest cable-stayed bridges. -- Samuel Wantman 20:49, 17 October 2006 (UTC)

[edit] Name of article

Wouldn't a better name for this article be "List of longest suspension bridges" rather than "List of largest suspension bridges"?

I now notice that this has already been discussed above. Notwithstanding the comments made earlier, IMO the page should be called "longest" rather than "largest".
