Windsor police say three people were taken to hospital after a multi-vehicle crash on E.C. Row Expressway.
Both eastbound and westbound lanes of EC Row were closed between Banwell Road and Lauzon Parkway for most of the evening as the accident reconstruction investigates.
Police say three people were transported to hospital with injures ranging from serious to life-threatening.
One person has since been released from hospital, but CTV News has learned two people remain in critical condition.
The road reopened in both directions before the morning commute on Tuesday.
