The Cascade Lakes Highway and Paulina Lake Road is set to close for the season on Tuesday morning.
Deschutes County announced last month that the gates will be closed and locked at 8:00 a.m.
With snow reaching five-to-10 feet at the road summit, the county says it’s cost prohibitive to keep the roads open and drivable.
Snow levels at some recreations along the highway have reportedly already reached levels that make them impassable for many vehicles.
Both roads will will be targeted for reopening prior to Memorial Day, weather permitting.
