Traffic backed up on a busy stretch of highway over the weekend due to what police say was "someone's idea of a practical joke.''
Portage la Prairie R-C-M-P received word Saturday that barricades were in the eastbound lane of Highway 1 at Highway 13, indicating that the highway was closed.
Police say numerous barricades and pylons had been moved from a construction zone in the westbound lane and placed in the eastbound lane.
Police say it could have caused a fatal crash, and they're still investigating the incident.
