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Aerial photos on Google and Yahoo are both out of date, so I can’t map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