Talk:List of longest masonry arch bridge spans

Minneapolis Stone Arch Bridge

I believe the Minneapolis Stone Arch Bridge is worthy of this list. Perhaps I am missing a detail, but the bridge spans over 2,000 feet (primarily due to its curved path across a wide part of the Mississippi River). There is an existing wiki at http://en.wikipedia.org/wiki/Stone_Arch_Bridge_(Minneapolis) 75.72.207.67 (talk) 01:48, 15 October 2009 (UTC)

According to the Stone Arch Bridge article the bridge is composed of: "Design: 21 stone arch spans, plus one steel-deck truss span; Total length: 2100 feet (640 meters); Longest span: 197.5 feet (60.2 meters) (channel span)". Apparently two stone arches were removed to be replaced by the steel span over the navigation lock. That span of 60.2 meters is made of steel and ineligible for inclusion on this list. Its size implies that the stone arches were about 60.2/2 = 30.1 meters and also too short for this list (whose low cutoff is 50 meters). An average of 640 meters/21 arches = 30.47 meters/arch and is also ineligible. If you can find a reliable source that documents that one or more of the 21 remaining arches made of stone spans at least 50 meters then the Minneapolis Stone Arch Bridge could be included on this list.69.115.42.244 (talk) 12:00, 1 November 2011 (UTC)

bridge removed

The Đurđevića Tara Bridge features an impressive main span. Unfortunately, according to the cited reference it is built of reinforced concrete and is therefore ineligible for inclusion on this list. 69.115.42.244 (talk) 11:47, 1 November 2011 (UTC)

Meaning of column "Arch type": ws = worked stone, uc = unreinforced concrete, rc = reinforced concrete (ineligible)

What about Chinese bridges?

As the main article text states, China has many of the world's largest stone masonry bridges, which it continues to build today. Why aren't they included in the list? Perhaps the 20 longest masonry bridge spans in the world are in China (ref), and this list doesn't mention a single one of them! Am I missing something, or is this just an appallingly incomplete list? -NoahElhardt (talk) 13:09, 23 April 2016 (UTC)
