All lanes of Highway 401 eastbound at Dixon Road are blocked, Ontario Provincial Police (OPP) say.
In a series of tweets just after 9 a.m. Sunday morning, the OPP Highway Safety Division said the lanes were blocked “due to icy roads that resulted in multiple crashes.”
Police said this included a “jack-knifed transport truck,” and a “rolled over truck and trailer” near Highway 409.
