Himalayan Balsam is a growing problem and Island 2000 have been working to control it for six years. Volunteers from Island Roads recently lent a hand.
The restriction has been imposed by Island Roads in conjunction with the Isle of Wight Council ahead of works to strengthen the listed structure, which are due to begin in September.
The work to upgrade a section of the A3054 from Eleanors Grove to Arnold Road, Binstead and including Quarr Hill, will be undertaken at night in order to reduce disruption.
