Debri after Hammersmith flyover heading toward staines

Was in the cage on the way in and had to stop in the centre lane as it looked like someone’s car had fallen apart in front of me.

Bumper, bolts, plastics no glass from what I could see but watch yourself.

traffic was too heavy for me to do anything about but I reported it on route to work.

oh meant to say this is just as you leave the flyover
