BOISE -- Boise National Forest officials say a section of the North Fork Boise River Road, Forest Road 327, is closed due to a river washout at mile post 30.
The road is used during the summer months for easier access from Highway 21 to the Middle Fork Boise River and Atlanta.
The prime alternate route is the Middle Fork Boise River Road.
A secondary alternate route is Forest Road 348 to its junction with Forest Road 327, which connects to the Middle Fork Boise River Road. That road is rough and not safe for passenger vehicles, or trailers.
The road surface at the washout is less than two feet wide. It is about 40 miles east of Boise in Boise County.
Repairs cannot be made until the river recedes and required fishery consultation is completed. Because of changes in river flow, the new road will moved to a rock outcropping adjacent to the old road.
