Overgrowth on pavement obstructing passage

There is very little room on the top pavement on Henbury Road, just left outside Hyland Grove. This is very dangerous, as cars pass extremely close to the pavement as the road is not wide. They also can be driving quite fast as there are no traffic calming measures. There is hardly any room to pass, and is particularly difficult for dog walkers, baby carriage pushers and the elderly, of which there are many locally. Please can someone come and cut back the verge? Thanks
