At about 10:15 a.m., the CHP was notified of lines down in the north- and southbound directions of Highway 101 between Marsh and Woodside roads, CHP Officer Ralph Caggiano said.
Traffic was stopped as crews cleared the cables from the roadway, Caggiano said.
The lanes were reopened shortly after 11 a.m.
Initially, the cables on the ground were thought to be power lines and PG&E crews were called to the scene.
No injuries were reported.
