I have actually seen some roundabout like constructs on parts of the interstate. They're giant, far larger than singular interchanges, and serve to handle multiple branches and belt loops.
Of course, they are augmented by allowing the main direction of travel to bypass the circle and go over/under it
Thank you for mentioning the asymmetrical traffic flow problem. YUMBL even managed to reproduce this using cities skylines, and there's an intersection near my house that's maddening for this. Large two lane circle, downstream from a traffic signal. When the signal is red you can use the circle normally. But when the signal turns green and there's a massive influx of traffic, forget about entering the circle from any point other than the one downstream of the light. Effectively one light controls two intersections
At a previous gig we had a simple "reset staging" task on gha, that ran once a week on Tuesday
It ran fine for years, then around November just stopped and never ran again. Tried moving it around for which time it would trigger, and it just never started again. Opened a ticket, and got nowhere
Having lived in West Richland before (in the Tri-cities, on Red Mountain, scrub and all), I don't think thats really true. Well, it is definitely sunnier than Seattle, but nowhere near Phoenix. It is more normal than special.
Barring that, 80%+ of the people in the PNW live near the coast.
Tourism board proudly advertises the 300 days of sun on big bill boards at the airport in Pasco, and the hot summers are honestly worse than Phoenix, as there's humidity
Phoenix can stay hot at night in the summer. Tonight is a good example. It's 90 all night and won't hit the low of 80 until 7am. This is borderline uninhabitable for many.
If you want the worst of both worlds with that kind of oppressive heat 24/7 and high humidity, take a look at Houston.
