Highway 401 eastbound blocked ahead of Thickson Road

A tractor-trailer rollover has blocked all lanes of eastbound Highway 401 in Whitby, creating a closure likely to continue through much of Tuesday's morning commute.

The OPP say the lanes are blocked just east of Thickson Road. There are two heavy tow trucks on scene and crews are working to clean up a large fuel spill.

Police are recommending drivers exit at Salem Road, Westney Road or Brock Road and use eastbound routes north of Highway 401, such as Taunton Road or Highway 7.

The OPP says the left lane will likely re-open at about 9 a.m., but the two right lanes will remain closed until around 12 noon.
