Bushes in the central reservation are overgrown and blocking pedestrains and motorist view

The central reservation is totally overgrown with self set Ash trees and other bushes. Whilst at the moment there are no leaves on these last summer they totally blocked the view for anyone trying to cross at the pedestrian crossing point. They also block the road signs for motorists and block motorists view of crossing pedestrians. I was advised when I reported this last year that the bushes etc would be cut back in the autumn. This has not happened and this will become a danger again once they come into leaf. This has now been an issue for over a year and is a terrible accident waiting to happen because of the view being so restricted by the overgrown plants along this entire section.
