[Talk-us] Divided diamond interchanges in the US
I recently stumbled upon an article[1] about the new use of the divided diamond interchange design in the US. It seems that the first one[2] is here[3] in Missouri and as yet unmapped. A second one in the same city is here[4], and it appears that the old interchange hasn’t been mapped either. Aerial photos on Google and Yahoo are both out of date, so I can’t map them myself. Is anyone in that area and able to update these interchanges? —Alex Mauer “hawke” 1. http://www.core77.com/blog/technology/video_visualization_of_a_new_type_of_traffic-improving_intersection_17734.asp 2. http://en.wikipedia.org/wiki/Diverging_diamond_interchange#Use_in_North_America 3. http://www.openstreetmap.org/?lat=37.24975lon=-93.31073zoom=15layers=M 4. http://www.openstreetmap.org/?lat=37.24975lon=-93.31073zoom=15layers=M ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

I've taken care of the new interchange at I-44 N Kansas Expressway since it's in NAIP but none of the others appear to have been constructed after the 2009 NAIP images were taken. Anyone know if there is any newer aerial imagery available? -- Jeff Ollie ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

You might also want to include the center sidewalk, as it's a rather strange configuration. ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

Not from what I could see from NAIP. It looks like it's there but not yet paved on that image; here's a photo showing that it's now open: http://www.flickr.com/photos/riffsyphon1024/4877762571/ You can also barely make out the sidewalks and crossings on the aerial. ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us

Looks like someone got to it already; I might be out that way but it'll probably be the summer before I'm out anywhere near there. signature.asc Description: OpenPGP digital signature ___ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
Re: [Talk-us] Divided diamond interchanges in the US
A friend of mine found a flickr set from MODOT with more aerial imagery (not rectified but high resolution) http://www.flickr.com/photos/26387...@n06/sets/72157621103069705 This makes it obvious that there is indeed a direct link over to Norton and that it is open as you can see cars driving on it. It is just concrete instead of blacktop like most of the intersection so it is harder to pick out. I have added it. After looking at the flickr pictures I feel that I can pick out the footways well enough from NAIP imagery to trace them as well. It looks to me like the island going across the bridge is intended for pedestrian use as well.
