Snow Zone Signs
Description
 
 
Person chaining up back tire on carChains Required roadway sign ODOT has approximately 150 signs throughout the state near mountainous areas that warn motorists when traction tires and/or chains are needed because of snow on the roadways. Previously, snowplow operators had to manually rotate messages on these signs during winter conditions. This took operators out of the vehicles and reduced the efficiency of plowing operations.
 
ODOT has now retrofitted 8 of these signs so that they can be changed remotely via a cell phone call. Seven of these signs are on Interstate 84 and one is on State Route 331.
ODOT has also installed dynamic message signs (DMS) in 6 other locations to warn motorists when traction tires and/or chains are needed.
