GLENN COUNTY, Calif. — Caltrans is alerting motorists that the long-term closures of the north- and southbound Interstate 5 Willows safety roadside rest areas, or SRRA, in Glenn County have been extended to March 31, 2022.

The Willows rest areas have been closed since January for construction and were originally expected to reopen by Dec. 31. However, a time extension is required because of supply chain delays for materials needed to complete improvements to the facilities.

During the closure, northbound I-5 motorists will be directed to use the Red Bluff SRRA in Tehama County, about 42 miles north of Willows; please note the northbound Corning rest area is closed for maintenance work.

Southbound motorists will be directed to the Maxwell SRRA in Colusa County, about 34 miles south of the Willows SRRA.

Caltrans is investing more than $6.9 million to update the wastewater, water, and lighting systems at the Willows rest areas. TSI Engineering Inc. of North Highlands, Sacramento County, is the contractor for the project.

Weather or unexpected events may delay or prolong the work. Caltrans advises motorists to “Be Work Zone Alert.”

The department will issue construction updates on Twitter @CaltransDist3 and on Facebook at CaltransDistrict3.
