We are being told of a collision on Highway 61 on the Kam River Bridge.
A witness who is stuck in a line of traffic tells our newsroom it happened around 10 pm this evening.
The person says a firefighter told him traffic could be backed up for a few hours.
Authorities are attempting to re-direct traffic onto Highway 130.
OPP are in the early stages of the investigation and so authorities are not able to give us more information at this time.
