Spring runoff has washed out a portion of Highway 28 near Redwater, Alberta Transportation said on Tuesday afternoon.
As a result, the route between Highway 38 and Highway 63 is closed to allow for repairs.
Repairs to replace two culverts are expected to take three to five days to complete, Transportation said.
In the meantime, traffic is being detoured along Highways 38, 644 and 829 through the Town of Redwater.
On average, about 5,000 vehicles per day travel along this portion of Highway 28.
