Another example in my area that just came to light in another thread:

The intersection of NY 15 (Mt Hope Ave) and Westfall Rd/Westmoreland Rd. in Rochester, NY was recently rebuilt. ...

https://www.google.com/maps/@43.1144766,-77.6224815,3a,37.5y,283.2h,93.86t/data=!3m6!1e1!3m4!1sneeiWnOEs4cpSgjJvcZFHA!2e0!7i16384!8i8192?hl=en&authuser=0



Maybe I'm missing it, but I don't see any lanes that disappear.  https://goo.gl/maps/SzjGRBnbWGY5X56z7  The left 2 lanes turn left into 2 receiving lanes; the right lane is a straight/right turn lane.

The 2 left turn lanes line up with only one left turn lane on the other side.

The proper alignment would include a buffer lane on the other side (example), or with the opposing left turn lane offset (example)

Neither are necessary. Some intersections that don't have the necessary width on the opposing side have these offsets. The pavement markings within the intersection are used when such a configuration exists.  Like this example, they have dotted lines thru the intersection to show the correct path to take.

See https://mutcd.fhwa.dot.gov/htm/2009/part3/part3b.htm#figure3B13 guidence 3: "...or where offset left turn lanes might cause driver confusion..."

There's dotted lines for the turn lanes, but that's standard for all double-left turn lanes. According to that guidance, there should be dotted lines for the through lanes as well.

Yeah for some reason I thought I saw them, but clearly not there.

I don't think this really counts but it fits with a lot of the other screwed up situations in this thread:

https://www.google.com/maps/@35.9164486,-82.0693671,3a,50.1y,121.42h,75.4t/data=!3m6!1e1!3m4!1sJZn8Da0nOuwJLfbYbMy9wA!2e0!7i13312!8i6656!5m1!1e1

This really threw me off during my first time in Spruce Pine, especially as a novice driver.
I love my 2010 Ford Explorer.

That absolutely counts. In fact it's very similar to the first one in the OP.

Like was just mentioned for the previous example, there's technically nothing wrong with it, but there should be pavement markings through the intersection.

Here's an example at Simpson Ferry and Allendale Roads in Mechanicsburg https://maps.app.goo.gl/SsXuNKG4rjK9qy266

I'm pretty sure this is what is being talked about.  https://goo.gl/maps/QuL26Af1QVwhr1496 .  WB State Street at Broad Street in Trenton NJ.  You may need to go thru historic GSVs to truly see it due to the road paint wearing off, but the left lane is a straight lane (GSV shows it being used for EB traffic due to utility work).  The right lane is a straight/right turn lane.  On the opposite side of the intersection, there is only 1 receiving lane for both thru lanes.  There's no taper area or anything - 2 thru lanes are forced to become 1 lane after the intersection.

Another example would be this:  https://goo.gl/maps/jLj1NuWHjScqHhJP6 .  Two lanes are marked for thru traffic WB to cross Rt. 45.  Once to the other side, the lane is about 20 feet wide, no markings, and it's just a single lane leading into a residential neighborhood.
