Radioyeg - Scanner Radio says a portion of Highway 21 was closed due to a multi-vehicle collision. 

According to the social media page, the highway in Strathcona County was shut down at Township Road 540 as of 10 p.m. It has since reopened. 

"One of the drivers involved apparently collided with two vehicles that were involved in a collision minutes earlier," the post says. 

Emergency crews responded to the incident. 

Road conditions on Tuesday were poor due to the heavy, wet snow.
