The third one is really odd. It's a 2 lane extended to the main road to allow access to an overpass.

Route 84 (Niles Canyon Road) and Main Street, Sunol, CA:

https://www.google.com/maps/place/Sunol,+CA/@37.5937724,-121.8918639,17.54z/data=!4m5!3m4!1s0x808fc23398d75b01:0x4494cb0395e64a97!8m2!3d37.5940369!4d-121.8884812

Historicaerials shows that this Y interchange has existed as far back as 1946.

Well, it looks like someone has never heard of the Blue Ridge Parkway...
If you ever feel useless, remember that CR 504 exists.

Strange proto-interchange between US-65 and the Lincoln Highway in Colo, IA.  At the time it was built, the Lincoln was still US-30.

Why would they build interchanges for 2-lane roads though?

There are areas where cross traffic/terrain make it beneficial to do so even if the roads themselves don't merit 4 laning.

Nope, US 20 is 3-lanes just east of the MA 140 overpass and continues as a 3-to-4 laner west of MA 140.

But that 3rd lane is just an aux lane.
