[Talk-us] Divided diamond interchanges in the US

[Alex Mauer]

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Aerial photos on Google and Yahoo are both out of date, so I can’t map 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?
