During severe weather, notices of road closures / road re-openings, snow plowing operations, and other safety advisories are posted on the NEW DPW Emergency Page at

You can also get immediate updates at and on the DPW Facebook page - SDCountyDPW

Safety Advisory:

During any period of severe weather and heavy rains, people need to be acutely aware of their surroundings. If you are driving watch for boulders that could come loose from mountainsides, or trees that may fall across the roadway, especially in periods of high winds and at night. Stay away from flooded rivers and streams, and do not try and cross flooded intersections or low water crossings. You have no idea how deep the water is, or in the case of the low water crossings, if the crossing is even intact. Remember, a small amount of water at the right velocity can sweep a vehicle and its occupants off the road and downstream. If you have to ask, "Can I make it?" - Don't even try. It's not worth it.

Roads Summary:
at and on and on Facebook at SDCountyDPW

Storm Activity:
Crews work around the clock during severe weather to keep our roadways safe and passable. Please be alert for County equipment operating, especially snow plows in the mountains. 

What you can do to help:
During the storm, some drains and culverts clogged with material washed down from upstream or illegally dumped at the roadside. If you see illegal dumping, please call our hotline at 877-684-8000, or notify local law enforcement.


DRIVING ADVISORY: Please always exercise caution in low-lying areas prone to flooding. Do NOT cross a flooded roadway if you cannot see the pavement. A few inches of water at the right velocity can carry a vehicle and its occupants off the roadway and downstream. In mountain areas be aware of mud flows, rocks and other debris in the roadway during and immediately following a rain event. Where ice and snow are present, exercise extreme caution and be watchful for County road crews and equipment. Also do not stop in the roadway to get out an enjoy the snow; find a safe place to pull over and park
