Butte County — Motorists can expect significant travel delays next weekend on State Highway 70 south of Oroville for roadway construction work.

A contractor will be conducting reversing one-way traffic control around the clock at the intersection of Palermo Road/Welsh Road and Highway 70 starting at 10 p.m. Friday, July 12 and continuing through 5 a.m. Monday, July 15. Flaggers will be stationed on both sides of the intersection directing traffic through the work zone. Motorists can expect delays of up to one hour.  

In addition, local residents will find Welsh Road and Palermo Road closed intermittently at Highway 70 throughout the weekend.

Caltrans advises motorists to use alternate routes such as Highway 99 to avoid the heavy traffic congestion in the area.

The work is part of a safety project to widen Highway 70 between Ophir Road and Palermo.

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.
