Blasting at slide south of Riggins to close both US-95 and Old Pollock Road tonight
RIGGINS—Both US-95 and Old Pollock Road are expected to close tonight from 3 to 4 p.m. PT / 4 to 5 p.m. MT to allow crews to blast an estimated 14,000 cubic yards of unstable rock from the slope at milepost 188. Just as much rock has already fallen to the road since the first slide on July 3.
After the blast, traffic will remain on Old Pollock Road until the slope is determined to be stable and crews can clear the detour around the base of the slide. Cleanup efforts are expected to take up to one week.

This is the first of two blasts planned to correct the slope failure. The second blast has not yet been scheduled.
After blasting, long-term repairs will include reinforcing the remaining slope with bolts and wire fencing.
Video of the first blast will be distributed in another release.
