The Ambassador Bridge connecting Detroit and Windsor, Ontario, shut down Monday night, according to the Michigan Department of Transportation. Protests over Canadian Covid-19 vaccine requirements had spilled over from Ottawa earlier in the day, and Windsor police said demonstrations were interrupting travel.
Canadian officials declared a state of emergency over protests in Ottawa over the weekend. Truckers had poured into the Canadian capital to decry vaccination requirements for cross-border travel.
Those protests spread on Monday, CBC News reported, and by Monday night, the busiest land border crossing in North America was shut down.
“We urge anyone involved in the demonstration to act lawfully, peacefully and respectfully,” Windsor police wrote on Twitter.
The Canada Border Services Agency encouraged travelers to reroute to the Detroit Windsor-Tunnel or the Blue Water Bridge, about 60 miles away.
