I guess the state is voting on this next week...
https://ktul.com/amp/news/local/most-expensive-highway-project-in-tulsaHere's the type of interchange I would have liked to see (only with 75 going above the ring)
works with the existing topography / reduces the number of entrance/exit ramps on I-44 and 75 / reduces 75 going down into the valley so much
edit: never mind / looks cool / seems like it should work
This three-level roundabout just outside Leeds, England, is perhaps most famous for how poorly it works, causing standstills during rush hour. The interchange was built in the 1970s, and has been unable to sustain traffic loads that pass through the area.
