Caltrans will pave Highway 116 from Cooper Road to Llano Road south of Sebastopol starting Sunday night.
The work will continue each night from 7:30 p.m. to 5 a.m. until Thursday, Caltrans said.
During the work, which includes grinding away old pavement and repaving the roadway, there will be one-way traffic control. Residents may notice more noise when workers are in the area, Caltrans said.
The work is weather dependent. If it is delayed due to weather conditions, it will be rescheduled for a later time. The California Highway Patrol will be on site during the construction.
