Hey shadowfoot. That's a dodgy bit of road aye? I've screamed through that underpass at 72kmh before - its a fast bit of road. In fact last year one of Auckland's road racers, Steve Parker was on the PnP Monday night bunch ride through kingsdale there, and did an attack at ~60kmh. Pedestrian walked out, he swerved and braked and went over the bars. He spent a wee while in Hosp, and is now steel reinforced. Count yourself lucky. Just take it easy through there buddy, hope you heal well.
