Towering brambles starting to grow across the path

The brambles along this stretch need to be cut back by a couple of metres as they are already starting to encroach the cycle path. My husband got his eye scratched as he cycled by from an overhanging bramble and as soon as they start growing for spring, which is now, they come right across the path. We cut them back to protect cyclists and dogs paws three times last year but they need to be done properly by the council to avoid this. Please could you give us a couple of metres of clearance to keep everyone safe. Thank you.
