Weird Georgia overpass

Can some explain why Georgia chose to do this?

I have seen the images. I am not asking if the route is wrong just why Georgia chose to do something like this. It doesn’t seem logical to me to split the street like this and have the streets cross themselves twice like that. Can anyone refer me to a news article or something?

Is this better? or are they planning something for the future to expand or something?

There’s been several threads about diverging diamonds over the years here.

I tried to post this in your unlock request thread but you deleted it before I was able to post it - check out http://www.cbsatlanta.com/story/18684639/traffic-begins-to-move-through-diverging-diamond-at-ashford-dunwoody

Thanks everyone for responding. I didn’t know what that thing was called so I had nothing to search for. So…, diverging diamond huh. Kinda cool name. Horrible concept. Now for some research. :slight_smile:

If folks could post examples of these in use in the editor, it may help.

Here is one I had to build.

Watch this youtube video:

You just might change your mind about the concept.

I’m not convinced. Sure the video makes it nice and even but real traffic patterns are far from ideal with drivers not paying attention and the natural slinky from accelerating cars. It might be working there I’m not sure. But how about pedestrians and bicycles. It looks like they need to go through the center of the bridge so have to cross like 6-8 lanes to get to the other side. If they don’t go through the middle then they need to cross where the cars are getting onto the freeway at full blast. If there is a light there it defeats the purpose. I think to make it really work it would need to be a double decker bridge or a “roundabout” bridge where cars don’t need to stop. I think I might have to take a trip to my closest diverging diamond and see for myself.
