A Winnipeg man is blaming a rough spot on I-29 for causing him to crash his pickup and trailer.

Bill Schmitke says he was driving north on I-29 around 2:30 this afternoon.

While he was heading over the overpass near Mayville, his pickup hit a bump and lost traction.

Schmitke's pickup and trailer landed on its side in the ditch.

He wasn't hurt.

He says drivers should be warned about the sudden bump in the road.

"That something like that isn't properly marked, the first aiders say that this is a regular scene of accidents here and why it wouldn't be properly marked, I can't believe it," said Schmitke.

Schmitke's wife was also in the pickup and was also not hurt.
