To me, at least, jersey barriers seem like a temporary thing, something that belongs in a construction zone, but not the finished product. If I’m being nit picky, I want the separation to be low enough that a pedestrian can step over it, too.
Best case scenario is obviously grade separation and distance between cars and bikes, but in a confined space, I dont think these barriers are horrible. Maybe the best move would be full-height barriers at the ends, and these low ones in the middle?

















The problem is mother nature tears down giant trees that provide shade (and look nice), and then the city replaces them with crape myrtle, purple-leaf plum, Bradford pear, and a whole bunch of other non-natives that dont grow tall enough to ever provide shade, and dont have any other benefit.
