A woman remains in hospital following a collision involving a bicycle and a semi-trailer in Winnipeg during the afternoon rush hour on Monday.

The crash happened at around 4:30 p.m. CT on Notre Dame Avenue near Keewatin Street.

The injured woman was initially listed in critical condition but was later upgraded to guarded condition.

A witness told CBC News it appears a female cyclist was hit by the truck as it was turning right onto Notre Dame.

The witness said the woman was conscious and screaming, and there was a lot of blood at the scene.

The back tire of the bicycle appeared twisted, and on the ground were some blood-stained blankets and a water bottle, the CBC's Gosia Sawicka reported from the scene that evening.

Police say the 25-year-old woman was riding her bicycle on the sidewalk southbound on Keewatin Street near Notre Dame Avenue when she got on the road while the semi was making a westbound turn onto Notre Dame from Keewatin.

While the woman tried to turn her bicycle back towards the sidewalk, the semi made contact with the bike and the woman fell to the ground, according to police.
