Temporary road around the base of US-95 slide south of Riggins to reopen tonight
RIGGINS—Traffic at the US-95 slide south of Riggins is planned to shift from the detour on Old Pollock Road to the temporary road around the base of the slide tonight, thanks to quick progress on cleanup efforts since the blast last week. The route could reopen as early as 5 p.m. PT / 6 p.m. MT, but drivers should check 511.idaho.gov for updates as the deadline approaches.
“We’re able to open this up much sooner than anticipated,” said Janet Zarate, co-manager of the repairs and materials engineer for the Idaho Transportation Department. “Both our contractors and our own employees have worked long hours over the last several days, putting us ahead of schedule.”
In addition to clearing the roadway, crews finished rebuilding protective berms to shield traffic from any additional rock fall.
Traffic conditions will be similar as before the blast, but drivers should plan for additional 30-minute delays as scalers on the slope dislodge loose material. Scaling will continue throughout the week but minimal traffic impacts are anticipated over the holiday weekend.
“In just a few short months, we will have built something that will protect drivers below for decades,” Zarate said. “The inconvenience of delays in the coming days will help keep travelers safe and prevent long-term delays in the future.”
Last Friday, both US-95 and Old Pollock Road were closed for half an hour while crews detonated 6,000 pounds of explosives, removing 14,000 cubic yards of unstable material from the slope.

A second blast in the coming weeks will address stability concerns for the adjacent slope to the south.
