Both lanes on State Highway 1, just north of Johnsonville have reopened following a crash between a motorcyclist and a car.
A police spokeswoman said the motorcyclist received moderate injuries and was taken to hospital following the crash around 5.50pm, prior to the Helston Rd overbridge.
Both lanes have since reopened after being temporarily closed.
A Stuff reporter on SH1 said traffic was at a standstill for about 10 minutes.
