Citybound commuters are experiencing up to 50-minute delays on the Bruce Highway as wet weather wreaks havoc on southeast roads, including a serious motorcycle crash.

There is also heavy congestion on the Logan Motorway westbound back to Berrinba, with generalised congestion of major roads due to wet weather.
