A friend/colleague of mine is on a long road trip out to California and back to visit relatives. He and his wife are taking a long, scenic route to and from.
He noted that the segment of US 412 between NE of Boise City and NW of Guyton is the longest single straight stretch of highway in the country.
He was also intrigued by the configuration of the intersection of US 412 and US 56, as seen thusly:

This is not dissimilar to the intersection of US 25 and US 421 here in Kentucky:

Before the intersection was rebuilt, what is now the intersection of US 62 and KY 11 in Maysville was a similar design.
What's this intersection called? I remember seeing a photo of the Maysville intersection many years ago with a descriptive term. Part of me wants to call it a "French weave" or "French braid" intersection, although I know that's not right. Possibly a "Carolina" weave or braid?
I don't know what you call it, but I can give another example of one: US 17 and Business 17 in Murrells Inlet, South Carolina (https://www.google.com/maps/@33.5285927,-79.0628037,360m/data=!3m1!1e3).

Your two links are identical.
As to what it's called, I'm not sure. Both your example and the one posted by US 89 are missing the left turn movement from the major road onto the minor one; not sure if that's just fluke or an actual defining feature of this intersection type.
Here's the second intersection HB was referring to:
Dropped pin
Near Battlefield Memorial Hwy, Richmond, KY 40475

Sometimes Command-C doesn't actually pick up the link. This appears to have been one of those times. Oops.

That looks like a fatal accident waiting to happen type of hell.
The first one looks like an at-grade Directional-Y (with single acute turn), and the other is just an at-grade Y.
We have several of those in Washington, albeit, most are light controlled.
SR 20 at SR 536 near Mount Vernon - https://goo.gl/maps/VJjhYqSrKeVnYenK7
SR 99 at I-5 (1) in Everett - https://goo.gl/maps/j2SaeSkePYFQq3pq5
Of course, both of those aren't as acute as the examples given.

Double mystery intersection. It's a roundabout now, but when it existed it caused major traffic problems since thru traffic on WI-19 east had to stop to traffic going from WI-113 NB to WI-19 WB. It was horrible.
Another Kentucky example:
