Highway 101 Still Sinking, Truck Traffic Restricted on Nearby Route

The 'Hooskanadan Slide' shifted on Monday, causing both lanes of Hwy 101 to buckle.

UPDATE: The south side of Highway 101 continues to move about 10 to 12 inches an hour, according to ODOT District Manager Darrin Neavoll. 

Neavoll says he is hoping it will start to slow down over the next few days. Movement on the north end has slowed. Starting tomorrow, officials plan to begin building a road on that end. 

Tidewater has been working to divert the water away from the main part of the slide. Officials have also been hauling in rock and storing it on the north end. 

Neavoll drove the detour on Carpenterville and said the overall flow of traffic is moving well in both directions. OSP will continue patrolling the road to make sure people drive slow. 

UPDATE: With the buckling roadway on Highway 101 continuing to move, ODOT has been unable to address a contingency plan for traffic in the area.

ODOT has now put a checkpoint in place on the nearby Carpenterville Road to prevent commercial semi-trucks from taking the narrow, winding route as a detour, according to Curry County Emergency Services. Most traffic can continue to use Carpenterville as a detour.

Meanwhile, the Hooskanadan Slide that has buckled the highway between Brookings and Gold Beach continues to move, Curr County Emergency Services said.

"Contractors are working to get Highway 101 reopened as quickly and as safely as possible. If you must travel between Brookings and Gold Beach along Carpenterville Road, please allow extra time for travel and drive cautiously."

ODOT said that it may have a low bidder for a contractor to repair the slide.

"But until the slide slows, work cannot begin. The slide continues to move at a rate of nearly two-feet an hour," the agency said.

For more specifics on freight restrictions, see the following:

 • 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.

UPDATE: The Hooskanadan Slide on Highway 101 north of Brookings continued to move on Tuesday, according to ODOT.

The agency said that the roadway was still buckling, moving about 10 feet "both horizontally and vertically."

"The goal, once it slows down, is to gravel a portion of the highway and get it open under 24/7 flagger control," ODOT said in a statement.

ODOT reiterated that commercial trucks should not be using Carpenterville Highway as a detour, and said that a checkpoint could be put into place on Wednesday morning to deter oversized vehicles.

INITIAL REPORT: Highway 101 remains closed on Tuesday morning about halfway between Brookings and Gold Beach due to a "sunken grade," according to the Oregon Department of Transportation (ODOT).

The closure is at milepost 344, about 12 miles north of Brookings. ODOT said that the spot is known to locals as the Hooskanadan Slide, which "abruptly shifted" following the storm system over the weekend and is apparently a chronic trouble spot on the highway.

“Hopefully, we can get a single lane open under gravel later today,” said ODOT District Manager Darrin Neavoll, “but given the nature of the sunken grade that maybe wishful thinking.”

Although the Carpenterville Highway runs nearby, ODOT said that it is a narrow and steep roadway and commercial traffic on that route — with the exception of logging trucks — is discouraged due to potential hazards.

"Through traffic should use alternate state highway routes," ODOT said.
