How can I place the image of the At Grade cloverleaf properly... what copyright tag do I use??? Route 82 02:35, 12 June 2006 (UTC)
The article seems uncertain what the plural is. Both "cloverleafs" and "cloverleaves" have been used. Choose one and use it consistently throughout. — Paul G 07:00, 28 May 2007 (UTC)
I've corrected the detail regarding cloverleaf interchanges in the UK. There were three originally, one in Redditch (mentioned), and two in Livingston, Scotland. One of the Livingston examples has been replaced with a more conventional partial cloverleaf as part of a bus route system.

Humm - interesting article, and I hate to accuse it of any bias (it is well written) - but it seems a tad skimpy on their history and popularity in the USA. Here in the USA, they're very popular, despite the drawbacks. Go on any highway in the USA, and you'll encounter dozens of diamonds and cloverleafs. I understand that in Europe, that may not be the case, but I don't think this is an article only about Europe. It's nice that the History section provides a lot of specific instances, but perhaps either the overview or the history should be expanded, adding a bit more detail on their general history? In addition, I think the statement that "They were used for over 40 years . . ." is inaccurate, as they are still used, and "were" implies they are no longer popular, which is certainly not the case in the USA. As far as I can tell, cloverleafs are still very popular on our interstate system, and I have witnessed construction of new cloverleafs within the past few years. They're not declining in popularity, because the only reasonable replacement to handle the traffic of two highways intersecting is the large and expensive stack interchange. Most of the other alternatives can handle large volumes of traffic in only one direction. — CobraA1 19:00, 2 January 2009 (UTC)
Yes, the cloverleaf interchange is still frequent in the U.S. where freeways intersect and traffic is not too heavy, i.e. outside of major metro areas. No, the stack interchange is not the only replacement interchange that can handle larger amounts of traffic (for intersecting freeways) - see for example the turbine interchange. But for any of the alternatives, overpass (flyover, bridge) costs will be 3 times as much, or more. This includes the collector/distributor version of the cloverleaf. -- 66.41.154.0 ( talk) 16:47, 3 September 2014 (UTC)

This clear and concise image should be usable; it originated from a government source ( North Carolina Dept. of Transportation).

The article mentions, and links to, cloverstack interchange as alternative configuration, but cloverstack interchange gets redirected to this same article. — Preceding unsigned comment added by 108.234.224.230 ( talk) 08:02, 10 November 2014 (UTC)
