Car rolls onto roof after hitting tollgate on Sydney Harbour Bridge

A car rolled onto its roof on the Sydney Harbour Bridge this afternoon after reportedly hitting the side of a tollgate.

NSW Ambulance crews were called to the scene at about 2.30pm with the male driver, believed to be in his 20s, complaining of a sore arm.

It is understood the incident occurred on a southbound lane of the bridge with the vehicle blocking traffic two lanes.

Live Traffic Sydney tweeted about an hour later that all southbound lanes of the Cahill Expressway were reopened after the car was towed away.
