ST. HELENS, Ore., Mar. 18, 2026 — Columbia County Public Works crews are responding to road damage and flooding caused by the recent atmospheric river event, resulting in multiple road closures and traffic changes across the county.

Apiary Road (Milepost 7.1), at Meissner Road – Traffic Revision
A culvert northeast of the Apiary Road and Meissner Road intersection has separated, partially undermining the north lane. Crews have installed temporary advisory signage and cones to shift traffic to the south side of the roadway while repairs are planned. Public Works crews will excavate the area, restore the roadway, and repair the culvert. Additional updates will be provided as repair work is scheduled.

Holbrook Road (Milepost 1.1), at Beaver Homes Road – Road Closed
Holbrook Road remains closed after floodwaters overtopped the roadway at Goble Creek. Water has receded, and a washout has been confirmed. Public Works crews are assessing the full extent of the damage and will begin repair planning, including restoring the roadway base and surface.

Detour: Holbrook Road → Fairview Road → Nicolai Road → U.S. Highway 30.

Heath Road (Milepost 0.2 to 0.45), between U.S. Highway 30 and Wonderly Road – Road Closed

This low-lying section of Heath Road is prone to flooding and is currently closed. Once water levels recede, Public Works crews will reopen the roadway and begin restoration work.
