For the past three weeks, 15 crews of electric line workers replaced hardware on more than 100 poles. The work happened in foggy, brisk conditions in rugged terrain overlooking the windy two-lane Highway 1.
Two helicopters also assisted by ferrying light-duty steel poles and other equipment to crews working in steep, hilly areas that were difficult to reach by truck.
PG&E officials say poor reliability in the area is due to hardware corroded by ever-present moisture and salt air. Electric transmission supervisor Bob Grantham said the type of corrosion is something not seen in inland parts of the state.
