Highway 401 was closed in the westbound lanes for several hours overnight, after a collision between two big rigs.
Around 8:45 p.m., emergency crews were called near the OnRoute west of Trenton, after one truck hit the back of another.
The load was spilled over the highway, closing the lanes.
The OPP re-routed traffic around the collision, by going through the parking lot of the rest stop.
Things were cleaned up and the road was re-opened just after midnight.
One driver was taken to Trenton Memorial Hospital.
