Traffic delays are being reported on State Highway 29.

A caller to the 0800 SUNLIVE news hotline says it appears a truck's wheel has come off.

"The road is down to one lane and traffic is jammed.

"Its on the road between Barkes Corner the The Lakes roundabout."

The caller says the truck is nera the little bridge on that stretch of road and advises people to take an alternative route.

SunLive is working on getting more information and will provide an update when we can.
