I am curious, how did you find those?
I like to think that it's (posh accent) "Yes good sir, I do indeed keep an extensive collections of references to exotic bridge layouts"
What would be neatest is to learn that there is an exotic geospatual query language. "no junction and road bend radius less than 20M within 50 meters of bridge"
But I suspect it is a well formulated web search "Complaints about right angle overpass"
And final thoughts, Your right, it is not much different than a common freeway offramp system. So I am not sure what the fuss is about. Perhaps too constrained, and it needs a larger turning area?
I just remembered that I saw a Reddit thread with some users posting other examples of this so I just clicked on the most upvoted post for this bridge and filtered the comments to those linking to Google Maps.
So sadly there was no exotic geospatual query language involved - although that would have been a way cooler answer. :/
in the 90s i built a webinterface for a database of architectural details for a university department. i don't know if it included bridges, but i am sure that some university departments teaching bridge building or traffic planning somewhere have a database of bridge layouts. maybe this one here: https://urbannext.net/
