Tyne Avenue missing road signs still not attended to

I previously reorted our speed signs and others were not clear to drivers of which there are many, we have down this road which is close to a school. Workmen did come and cut back some of the branches and cleared it for the pelican crossing BUT there are still 3 signs on one pole that have not been attended to. I cannot take a photo as I cannot see them from the road and the branches need attention. You say these 3 signs are the responsiblity of owners of this private land but this cannot be correct as the signs are to do with things along this road, such as a Raised Crossing called a Hump, which a council would be reponsible to ensure safety for local drivers.
