Crews with PG&E are planning to move a utility pole at Highway 1 and Highland Drive in San Luis Obispo.
Cal Trans officials say the work will take place from 9 p.m. on Monday to 6 a.m. on Tuesday. During that time, the intersections will be in emergency flash mode.
According to Caltrans, the work will help prepare for the Highland Improvement Project, which is expected to break ground in late December.
