Canadian workers for the Blue Water Bridge went on strike this week.
The 45 employees, who all work on the Canadian side of the bridge, are picketing due to contract disputes.
Jocelyn Hall, a media contact with the Michigan Department of Transportation, said the strike could make holiday travel difficult.
“As a contingency plan, a staff of non-unionized employees are filling in those roles and that capacity to keep traffic flowing,” Hall said.
Hall says if there is any traffic backup, it would more than likely be on the Canadian side of the bridge.
