Police and paramedics are currently in attendance where Eleanors Grove meets Quarr Hill on the main road between Binstead and Wootton.
Island Echo understands a motorcycle – a scooter – has left the road on a long right hand corner, coming to rest in amongst the trees down a slight embankment on the outside of the bend.
The Isle of Wight Ambulance Service is on scene with paramedics tending to the injured rider, who is thought to have sustained head injuries. His helmet has been seen at the side of the road some distance away.
Traffic is heavy in the area but the road remains open, under Police direction.
UPDATE @ 10:05 – Police have now closed Quarr Hill in both directions between Fishbourne traffic lights and Binstead Hill.
The closure of the main road between the towns of Ryde and Newport is likely to cause significant delays for motorists, with alternative routes including Havenstreet and The Downs.
Southern Vectis Route 4 and 9 buses are being impacted by this closure.
The road is expected to remain closed for the rest of the morning, with access to the ferry terminal maintained from the Wootton approach.
UPDATE @ 10:20 – It has been confirmed that a 30-year-old male from Newport is being treated for serious injuries following the single-vehicle collision.
4 motorcycle-riding officers from the mainland-based Roads Policing Unit – on the Island for a pre-planned operation – are now attending the scene of the crash.
UPDATE @ 13:07 – Quarr Hill/Eleanors Grove has now re-opened, Police have confirmed.
