Innovative, Unique, or Strange Lane Markings

It looks to me like the onramp from Brook Avenue is close enough to the offramp from Taft that people were having trouble getting out of the lane on time, so TxDOT striped it that way to give them a place to go rather than forcing them to get off at Taft.

Minnesota says, —Then this is how you stripe that.

Not sure if this really counts but there's a freeway ramp from CA-91E to Albertoni St that folds over and merges onto a parallel one way street, forming a two way. There seems to be a vestigial lane for westbound traffic that goes unused. The exit ramp becomes its own lane, and the vestigial lane becomes the left lane, despite there being seemingly no way to get The road screams "I used to be a two way street until the freeway was built", but this configuration remains constant back to the 70s, as thats the oldest historic imagery I was able to find online. I believe the freeway predates the imagery by a few more decades.

Technically it seems legally driveable, as there is only one set of double yellows, as there is no one way signage or U-turn prohibition, and the lane doesn't become gridded out until further down. It seems ambiguous as to exactly where it ceases to legally be a westbound lane and becomes a left shoulder. California does occasionally mark left shoulders with double yellows. The road was recently repaved and even the vestigial lane was repaved, and the grid markings were never extended back towards the median.

Also of note: The dirt patch where a large number of cars that cut the ramp and turn left where the vestigial lane begins, although looking at the road geometry there seems to be no good reason to do so, as nothing connects directly to Albertoni between this exit and the next exit to Central Av.

On the topic of ghost lanes, we have US-101N at CA-170N, where after the split, the shoulder suddenly becomes the right lane at the same time a carpool lane spawns on the left. This one is pretty well known tho. Havent researched this one, but it seems to be a relic back when Caltrans was really lazy and expanded freeways by just deleting shoulders and narrowing lanes, rather than building new pavement.

GSV shows the car blatantly driving in the gore before the lane legally begins.

Looking at the grid overall, it seems plausible that Rainsbury might have been planned to extend to Albertoni, but perhaps neighbors protested and the plan canceled. The ROW on the left (judging from the fence line) sort of curves towards Albertoni and the corner itself still has stop signs, perhaps dating back to when it was planned to be an arterial intersection. It also seems to be the exact point where that westbound lane begins.
