SALEM, Ore. (AP) — Efforts to fully assess a landslide blocking River Road South in Salem, Oregon will have to wait.

The road is expected to remain closed between Owens Street SE and Minto Island Road SE, the entrance to Minto-Brown Island Park, for several days, according to city officials.

Officials say it’s not yet safe enough for teams to begin clearing debris that led to the closure or further assess the stability of the hillside. With snow and freezing temperatures expected early next week, the road could remain closed for seven to 10 days, the Statesman Journal reported.

The city will prioritize clearing of detour routes in the area while the closure is in place.

An early estimate put the amount of material that slid down at about 150 cubic yards, which is blocking the shoulder, northbound lane and spilling into the southbound lane, according to Courtney Knox Busch, a City of Salem spokesperson.

No injuries were reported following the slide, which was first reported at about 2:30 a.m. Thursday. Croisan Creek Road S is the designated detour route.
