Roadwork continues through September into fall. Caltrans reminds you that Paving operations continue on State Route 32, from about 6 miles east of the Butte/Tehama County line to about 5 miles west of the junction with State Route 36. You should plan for up to 30-minute delays, Monday through Friday, during daytime hours. Work is anticipated to be completed by early November, but weather, temperatures, and operations can change that. Other work in this area includes shoulder backing, guardrail upgrades, and striping.
In addition to the 30-minute delays through the Jarbo gap and Greenville wye along SR 70, you can add 10 minutes as Caltrans is set to complete more culvert work near Grizzly Creek Bridge. Caltrans will begin work on Sept. 19 to improve water drainage by replacing four culverts just west of the Grizzly Creek Bridge to the west of Twain Road. There will be one-way traffic controls throughout the area from Monday – Friday during daytime hours. The project is anticipated to be completed by the end of October.
Roadwork along HWY 139 continues as well; five miles north of the intersection of State Route (SR) 36 and SR 139 is the ongoing antelope drapery project that includes scaling loose rock from slopes and placing the drapery system; you can expect up to 15-minute delays through this project area. Further up 139, the Slate Creek 3-Layer Project will replace asphalt concrete surfacing via dig-outs and place an asphalt rubber chip seal and hot mix asphalt overlay on State Route 139 approximately 37 miles north of Susanville, from 4.3 miles north of South Grasshopper Road to just south of Termo Grasshopper Road. The project will also include shoulder backing, upgrading of guardrail to meet current standards, and striping. Both projects are expected to be completed by October.
