It was a deadly long weekend in Saskatchewan, with five people dying on the roadways.

The most recent fatality was Sunday just before 9:30 p.m, CST, when a 19-year-old woman was struck by a vehicle while walking on Highway 11 northwest of Regina.

According to the RCMP, witnesses said the woman was walking in the middle of the highway near the weigh scales between Regina and Lumsden.

An autopsy has been scheduled and the investigation is ongoing. 

The worst of the three weekend crashes was on Saturday, when three people died after the pickup truck they were in crashed into a road grader on a grid road near Punnichy.

Two men died at the scene while a woman who was airlifted to hospital died later.

The three others riding in the truck, including the driver, are being treated in hospital. The driver of the grader came away with minor injuries. 

RCMP say charges are pending in the crash between the truck and grader.

A woman whose car hit a moose died on Friday.

It happened near Bankend, Sask., at around 10 p.m. The woman's car hit the animal on Highway 35 and landed in a nearby body of water.

The woman, 23, was found dead at the scene. 

The coroner's office and RCMP are investigating. An autopsy for the woman has been ordered for this week. 

Names of the victims haven't been released.
