Parks Canada is warning drivers to be on the lookout for wildlife as recent heavy snow has covered over animal barriers known as Texas gates, or cattle guards. 

Texas gates consist of a depression built in the road, covered by metal bars, preventing animals from walking through. Officials are asking drivers on the Trans-Canada Highway to pay particular attention for animals on the road or in the ditches at the entrances and exit ramps to the Banff townsite, along with other interchanges in the park.

Parks Canada says it has started to remove snow from around and under the gates, but the job is time-consuming and may not be finished by the end of the weekend.
