Highway 58 is still closed at the Thorold Tunnel in both directions after a fire.
A vehicle went up in flames shortly before 3 o'clock this afternoon inside the tunnel sending smoke into the sky.
There were several cars inside the tunnel at the time, and some drivers abandoned their vehicles and exited the tunnel on foot.
OPP tell us there are no reports of serious injuries.
The fire has been put out but officials need to assess for structural damage, and that could take some time.
OPP say the ETA for re-opening is 'unknown at this time.'
