Vasco da Gama Bridge article -- Where is this bridge located? What country? What state? What city? What body of water?
[edit] Span
What is length of main span? Tabletop 06:12, 26 Mar 2005 (UTC)
[edit] Length
The article mentions different total lengths, the main article says 17,200 m (56,381 ft) and the infobox says 12,300 m (40,354 ft). Which is correct?

- Measuring the length on GoogleEarth and being very generous, I don't get more than 10,400 m - something very wrong here....Paul venter 20:50, 23 August 2006 (UTC)
- It all has to do with the definition of "bridge". In truth, the bridge is only 450 m-long. The rest are viaducts. But, as the viaducts go over the river and marshes, they are counted in as well. The south-side viaduct ends almost at the petrol station here: http://maps.google.com/maps?f=q&hl=en&q=lisbon,pt&ie=UTF8&ll=38.727606,-8.990765&spn=0.004294,0.010729&t=k&om=0 . Now you can measure again. --maf 11:51, 24 August 2006 (UTC)
- Err, actually I went there and measured it myself. I got 12,500 m on the outer lane. Could that be the 12,300 m that were initially in the infobox? And where do the other 5,000 m come from - access viaducts? That would be cheating! I'll look for some reliable source before changing the article. --maf 03:08, 14 October 2006 (UTC)

12,300 m is the total length over water, 17,200 m is the total length of the structure, including the viaducts aver the land/swamp lands.
