Ada County Highway District hopes to unveil an online map soon that will show which streets in the county have been plowed or treated with salt, sand or magnesium chloride.
The map, which will be on the highway district’s website, will shade recently treated streets in colors ranging from light to dark pink, spokeswoman Nicole DuBois said Thursday. The darker the shade, the more recent the treatment. The map will be updated every 12 hours.
“This map is not intended to be used to say, ‘These streets are safe,’” DuBois said. “It’s still winter driving conditions, so people still need to use caution.”
The map is one of many changes the district has made following last winter, which was so difficult it earned nicknames like “Snowpocalypse” and “Snowmageddon.” Other innovations include adding blue dye to salt so that people know which areas have been treated and putting residential streets on the list of snow-clearing priorities — albeit at the bottom of the list.
Never miss a local story.
DuBois said the map probably won’t identify which types of treatment — plowing, salt, sand or magnesium chloride — have been applied on the shaded streets. She said the district keeps track of these treatments through feedback from software on its trucks, but the map won’t reflect that information.
DuBois said the district hasn’t set a date for unveiling the map.
