Caltrans next week begins work on a stretch of Highway 20 commonly used by North Coast drivers to go to Shasta, other parts of the Sacramento Valley or points north, so some traffic delays are likely.

The project will cover a 14-mile stretch of Highway 20 in Colusa County, basically from where the road comes out of the foothills west of Williams to just east of Interstate 5.

The $8.3 million grinding and repaving project will run 7 a.m. to 4 p.m. Monday through Friday next week. Starting Monday, April 30, the work will be 24 hours a day Monday through Friday for about three weeks, Caltrans spokesman Gilbert Mohtes-Chan said. Drivers can expect delays of up to 15 minutes because of one-way traffic controls, he said.

No work will be done on weekends, so both lanes will be open.

In about a month, the project will switch to finishing work, such as striping, for a few weeks from 7 a.m. to 4 p.m. Monday through Friday for six to seven weeks, Mohtes-Chan said.
