Provincial police spent the morning dealing with multiple issues on the 400-series highways around the region Tuesday.
The 402 eastbound at Hickory Drive in Strathroy reopened around midday after being closed due to several collisions.
There were reports of at least half-a-dozen vehicles in the ditch including rollovers.
No serious injuries were reported as a result of the collisions.
Highway 401 eastbound was also closed at Veterans Memorial due to multiple collisions but has since reopened.
Drivers are reminded to go slow in snow and to avoid unnecessary travel while the issues are being resolved on the highways.
