Potholes so dangerous to riders of bikes

The potholes around Sutton Bridge are a severe danger to those, often young people, without much road experience, who are riding small wheeled 50cc motor scooters in the area. It's obviously worse during the winter months when dark, wet and gloomy and the young people are heading to and from their first job or education. One place which absolutely terrifies me is the island on the A17 with the B1168 (Boston Rd South) which leads to Holbeach Tesco. Anyone travelling by bicycle, scooter or motorcycle from Sutton Bridge to Spalding and who is therefore going straight on at that traffic island is at serious risk of coming off their bike for there is a deep gouge dug into road possibly by some kind of farm machinery, and should a bike front wheel get caught in that deep groove, which runs almost 1/4 of the distance around the island, they'd unlikely be able to correct themselves and get out of it without coming off their bike. As a leader of a bikers group I have warned my members but it's not enough. It's been there forever and is constantly overlooked because those at LCC are not bikers. Send one there to see for themselves. It's long overdue, I know it's been complained about each year.
