After an early heat wave in June and this last week of extreme heat, Idaho Highways 8 and 9 in Latah County are showing stress.
“Oil is flushing up to the surface of both highways, which can make for slick surfaces,” Operations Engineer Jared Hopkins said. “We want drivers to show more caution and know that we will continue to use fine sand to blot the moisture and keep the highways safe.”
Sections showing stress include ID-8 near Elk River and ID-9 near the ID-8 junction outside of Deary. Segments of these highways with curves, inclines or intersections where there is also heavy or turning traffic are more likely to be affected.
Over the last week, crews have also removed material to provide a better surface on select sections of ID-9 that received a sealcoat in 2020. Another project will be programmed in the coming years to rehabilitate the driving surface.
