Thank you for contacting Highways England regarding graffiti. I appreciate you taking the time to bring this matter to our attention.
I have forwarded your concerns to our maintenance team. Graffiti that is obscene or offensive will either be covered or removed as quickly as possible.
Removal of graffiti may require specialist equipment or lane or road closures to keep our workforce safe. This means that it is not always cost-effective to remove it as it appears. Therefore, graffiti which that is not offensive or obscene will be recorded and removed during the next round of periodic cleaning.
Thank you again for bringing this to our attention. Kind Regards Highways England
