It happened before midnight at Central and Dickenson.
California Highway Patrol officers say a pickup was northbound on Dickenson approaching Central when the driver possibly dozed off and drifted to the right shoulder.
A PG&E pole was sideswiped and came crashing onto Dickenson. The driver was not hurt, but the pole fell and brought down a live wire.
PG&E de-energized that line and the roadway was opened after 1 am.
About 50 PG&E customers in the area lost power.
