I suspect that the road originally kept straight so that is why there is that T intersection.To be fair they did put in a run off and it lead back to where you needed to go. I think you took the nicer route :-D
There is a brief sign at 16 seconds or so but it seems it is not that noticeable. Not like all like pictures here...Wow, pucker moment! No signage, either! Around here, they'd have those yellow arrow signs pointing in the direction the main road went, or a sign with a diverting road on it or something. I mean, people would still miss that [unless their stupid phones told them], but I digress...

If you missed and I missed it in real life then we either need new eyes or they need better signageYeah, I rewatched it to see if I saw a sign, and I did not. It did not open my mind.
