OLD FORT, B.C. -- A slow-moving landslide has closed the only road into a small community along British Columbia's Peace River for the second time in less than two years.

Residents of Old Fort, B.C., are on evacuation alert and the Transportation Ministry says Old Fort Road is closed except to emergency vehicles.

The B.C. government says localized ground movement was detected Thursday evening but there was no movement detected near residences and the road is closed as a precaution.

The Peace River Regional District issued an evacuation alert Friday evening for the Old Fort subdivision, warning that the road would be closed overnight and Saturday morning.

The alert says anyone not prepared to shelter in place should consider leaving the area in case the situation worsened and the road remained closed.

Residents of Old Fort, which is a 15-minute drive from Fort St. John, were evacuated for about a month in fall 2018 because a mudslide blocked the road.
