50-100 feet South of Stewart Hall on A4010 just North of Little Kimble Station

Travelling North at night on A4010 just past Little Kimble Railway Station. A vehicle had pulled over with it's hazard lights on and was being dealt with by a tyre recovery truck. The road is completely unlit, it was night time and weather was poor (raining). As I slowed and manoeuvred around the stationary vehicle, I struck something which caused rapid deflation of my driver's side front tyre. As I pulled over, it became apparent this is a previously damaged island/bollard and should have signage and be lit. I would like it known that at the time there was NO signage present at all (see photo of post laying flat to the ground which had already been hit previously). This incident has caused damage to my vehicle, cosmetically to the wheel, and a tyre has had to be replaced at considerable expense. The dark photo you can see is how the road appeared to me (using an extremely bright torch at close range). Note: The sign placed over the damaged bollards you can see was not there at the time; that was placed there by two Police Officers who arrived afterwards in an unmarked Volvo Estate. The ditches and road are strewn with debris and there were another THREE vehicles outside Stewart Hall some of whom were being tended to by the RAC, all of which who had suffered as a result of this. This is causing absolute havoc and is dangerous. The Officer's who arrived simply placed yet another Police cone at the scene. This is not enough! It needs to be illuminated with emergency flashing beacons as a minimum. I have many more photos of the scene from the day after when my vehicle was recovered. I would like to know how I claim against Buckinghamshire Council. They have a duty of care to ensure issues like this are dealt with properly and have failed to do so. Thank you.
