SR 20 icicles - Dec. 15, 2008
If you drive SR 20 during the summer, you may not think much of the water that seeps through the rock as you pass through the tunnels east of Newhalem. But in the winter, when the weather drops below freezing, that water can become a hazard for drivers. The icicles that form on the walls and ceiling can get so large that they nearly impede traffic. And the constant dripping of water onto the road creates several icy patches.

Our maintenance crews keep a close eye on the icicles and the ice on the roads. When the icicles get too large, they have to drive up and break them off. And they make sure to heavily salt and sand the icy patches in the tunnels so drivers can get through safely.
