The Ambassador Bridge was partially shut down Sunday night.
Police say they were investigating a suspicious package found in a vehicle on the bridge.
Police first tweeted about the shutdown around 9 p.m. local time, saying the bridge on the Canadian side will be closed for an undetermined amount of time.
At the time of publication, some traffic was being diverted to the Windsor-Detroit Tunnel.
“[Police] took all the cars away and sent them to the tunnel and they made all the trucks park in the compound at [the] duty-free. There’s about 50-75 trucks,” Todd Marciano, a trucker stuck on the U.S. side of the border, told CTV News.
He noted trucks and cars going into the U.S. weren’t being delayed, only those entering Canada.
“We’re kind of tossing back and forth the idea of staying [in Detroit overnight] or leaving to drive to Sarnia. My company is wondering how they’re going to get the trucks back because they need them Monday morning.”
