The Ministry of Transportion has two overnight closures planned for Thursday.
Starting at 10 p.m., the 401 Eastbound on-ramp from Highway 6 North will be closed.
One lane on the 401 Eastbound at Highway 6 North will also be closed.
Both are set to re-open Friday morning at 5 a.m.
The closures are in connection to ongoing clean-up efforts after the earlier fuel spill in that area.
