A landslide continues to block a scenic section of Oregon’s southwestern coast on U.S. 101 between Brookings and Gold Beach.

Dan Latham, an Oregon Department of Transportation spokesman, said the landslide began Monday near Hooskanadan Creek about 20 miles north of Brookings near milepost 344.

Latham said the area, which is along the Samuel H. Boardman State Scenic Corridor on U.S. 101, has been a problem spot for landslides since the early 20th century. This slide was triggered by heavy rains.

“This is something that we deal with every year,” Latham said, “but this is the largest since 2005 or 2006.”

The slide covers a 125,000-square-foot area of coastal highway and stretches just under one-quarter of a mile.

Latham said the “dramatic” slide continues to move at a rate of about 2 feet an hour.

ODOT is rerouting traffic onto Carpenterville Highway, a long, narrow, windy road that runs parallel to U.S. 101. The detour includes steep grades and an elevation change of about 1,700 feet.

The state has hired Tidewater Contractors out of Brookings to at least make the highway passable with two lanes of gravel.

But those contractors, who are working on a roughly $300,000 agreement, can’t start working until the weather lets up and the earth stops moving. It’s unclear when that may be.

A state geologist is on the way to the landslide area to assess it, Latham said.

ODOT plans to repave the road once it’s stable, but when that will be, too, is unclear.

Here are the freight restrictions, according to a news release:

Truck tractor and semitrailer combinations (fifth-wheel hitch) - 60 feet overall length, 40-foot trailer length.

Truck and trailer combinations (pintle hitch) - 65 feet overall length, 40-foot trailer length.

Doubles combinations - 65 feet overall length, 40-foot trailer length.

Other length limits as shown on Group Map 1
