Back in the day when you crossed the Canning town bridge and turned right to go silvertown, I was coming in from the Barking area. I stopped outside a post office to phone in and a bedford dormobile stopped at the lights where I would have been with the ERF I was driving. As I was walking across to the phone box a tipper (whoda thought it) came belting across the bridge to make the right turn towards silvertown. His o/s/r wheel hit the keep left island and he ended up on top of the dormobile. The driver was trapped but not badly hurt. The tipper was airborne when he hit, so if that had been me, I might have lost me legs, or worse.
