A single-vehicle crash involving a tractor trailer shut down the Hwy. 401 eastbound on-ramp to Belle River Road for several hours overnight, but the ramp is open now.
The Ontario Provincial Police say the tractor-trailer went into the ditch on Sunday night, and the closure was necessary to facilitate the investigation.
Police didn't say if anyone was hurt. A release from the OPP stated the "extent of any injuries is unknown."
The ramp reopened around 12:30 a.m.
