The Idaho Transportation Department has just sent out notice that a culvert running underneath Idaho 3 near Rose Lake (Milepost 113.8) has collapsed, washing out a portion of the roadway and forcing the closure of the highway.
High run-off and flooding in the area caused the collapse.
A new culvert will be installed and the roadway repaired. ITD will keep the highway open (one-lane, one-way) through the night and wont close the road until the contractor has assembled everything on-site sometime tomorrow morning. Then the closure will last a couple days.
At that time, you will need to find alternate routes. Commercial truck traffic will be re-routed from Interstate 90 to U.S. 95 and Idaho 5.
