A slip at the bottom end of Portal St is restricting access to Wanganui's Durie Hill.
Part of the hillside directly in front of a Rees St house perched precariously above Portal St came down after damaging rains swept the city on June 20-21.
The sole occupant of the house was evacuated.
Late yesterday Wanganui District Council engineers said Portal St would have to be closed until further notice and issued traffic diversion notices.
But by 4.30pm the situation had changed, with engineers saying that containers would be positioned beneath the slip to stop material falling across the road between Anzac Parade and Forres St.
