Two lanes of northbound Interstate 5 north of Woodland will remain open with a single lane closed indefinitely.
As debris clearing progressed from a recent landslide, geotechnical engineers from the Washington State Department of Transportation continued to monitor the stability of the slope and determined further analysis is needed before all lanes reopen to traffic.
“By keeping a single lane closed, traffic will continue to move safely while we develop our next steps for stabilizing the hillside,” said WSDOT Southwest Regional Administrator Kris Strickler. “We appreciate the hard work of the crews clearing the debris from the slide and appreciate the patience from the traveling public.”
There is no risk of additional debris falling into the open lanes of travel because concrete barriers separate two lanes of I-5 from the work zone adjacent to the nearby hillside. WSDOT will install monitoring devices this weekend to track potential for further movement of the slope.
The Dike Access Road on-ramp to northbound I-5 will remain closed and a reduced speed limit of 60 mph will remain until all lanes reopen to traffic.
The work is part of a cleanup effort from an emergency closure of all northbound I-5 lanes following a debris and rock slide on Wednesday, Dec. 9.
