Drivers can expect overnight delays along State Highway 20 east of Marysville starting tonight, as Caltrans repaves about half a mile of roadway.
One way traffic controls will start around 6 this evening and will likely continue until 8 Tuesday morning.
Caltrans anticipates the work continuing nightly, finishing Saturday morning.
Less disruptive delays are anticipated next Monday and Tuesday when crews will replace pavement on a local bridge.
The work, in the vicinity of Smartsville, is among nearly $30 million worth of repairs and improvements for highway 20.
