Old Siskiyou Highway to close because of landslide

A fast-moving landslide near milepost 6 of the Old Siskiyou Highway will close the road stretch to all vehicles Tuesday, May 1, Oregon Department of Transportation officials said.

"The slide is moving too fast due to spring runoff," ODOT District Manager Jerry Marmon said in a news release. "As these conditions could jeopardize safety. We need to close the highway until the slide dries out enough to let us go in and repair it."

Marmon added the area has been slide-prone historically, especially over the last several years, and that heavy rainfall necessitated repairs almost every day.

During repairs, ODOT geologists will take measurements of the water table and slope movement at the site. The results will determine how extensive highway repairs will need to be.

Motorists can take Interstate 5 to exit 6 or the Greensprings Highway to Old Siskiyou Highway to navigate around the slide. The alternate routes will add about five minutes of commute time for drivers.

Signs will also be posted today to remind motorists about the closure.
