BUTTE COUNTY — Construction crews are scheduled to start overnight roadwork next week on a three-mile segment of State Highway 70 south of Oroville.

Motorists may expect one-way traffic control from 8 p.m. to 6 a.m. Monday, August 3 through Friday, August 7 for pavement grinding, striping and K-rail installation work between Palermo Road and Cox Lane. After this operation, crews will be working behind the temporary concrete barrier during daytime hours and no lane restrictions are anticipated at this time.

As part of a Caltrans work zone safety initiative, the speed limit will be reduced from 55 to 45 mph in the construction zone. Radar speed feedback trailers are in place along the highway to remind motorists of the driving speed.

The work is part of a $42.1 million project that will construct a continuous two-way left turn lane, widen the existing two-lane highway to a four-lane highway with a median turn lane with 8-foot shoulders, upgrade drainage systems and establish an area for vehicles veering off the roadway to return to the main highway. Knife River Construction of Chico is the contractor.

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.
