The 400 Highway is a busy stretch of road to begin with and an accident this afternoon has brought traffic to a halt.
A dump truck rolled down an embankment and into a ditch. Police that were on the scene just south of King Road say the driver was transported to hospital with minor injuries and the small fuel spill has been contained.
All northbound traffic was diverted off the highway completely at Teston Road, but now two lanes have been reopened.
Another collision near Major MacKenzie Drive has also been reported.
