Construction on a new left-turn lane on Highway 246 will begin on Monday.
The lane will be at the Foley Estates between East Campbell and Drum Canyon Roads near Buellton.
Roadwork will run from 8 a.m. to 4 p.m. Monday through Thursday and 8 a.m. to 2 p.m. on Friday.
Drivers in the area will encounter a lane shift for the installation of protective barriers for workers. Flaggers will maintain traffic control but delays are not expected to be more than 15 minutes.
