The on ramp has since reopened after a crash on Wednesday just outside of Morriston.
On April 15th at around 4:15pm, Wellington County OPP responded to a single tractor trailer roll over on the on ramp to Highway 401 from Brock Road South in Puslinch.
As a result, all lanes were closed on Highway 401 westbound off ramps.
One person was taken to hospital with non life threatening injuries with the road reopened before 10pm.
