Motorbike rider dies in high speed crash

The Gateway Motorway in Brisbane needed to be closed after a fatal motorbike accident early Sunday morning.

Police say initial investigations suggest the bike was travelling at high speed when it slammed into a guard rail northbound, between Mount Gravatt Capalaba Road and Old Cleveland Road around 1am.

A 30-year-old man died at the scene.

The Gateway was closed for an extended period, but has since reopened.

The Forensic Crash Unit is investigating.
