A Canadian judge granted a court order Friday to end a truckers’ blockade of the Windsor Ambassador Bridge, a vital trade route with the United States that connects to Detroit.

The injunction, approved by the Ontario Superior Court of Justice, was sought by the city of Windsor and the Automotive Parts Manufacturers’ Association. Chief Justice Geoffrey Morawetz said it would go into effect at 7 p.m., but reports from the scene indicated that the crowd was not quick to leave. The city and association argued that they were losing as much as 50 million Canadian dollars (roughly US$39 million) per day thanks to the convoy, which has blocked off the bridge since Monday, according to the BBC.
