The accident happened about 4:30 a.m. when a big rig driver failed to negotiate a curve when he was traveling northbound on Grant Line Road south of White Rock Road. The trailer hit a power pole and lines started to arc.
The lines lowered and were still blocking Grant Line Road two hours later. The driver was not injured.
No estimate was available for when the road would re-open. Alternate routes are Douglas Road, White Rock Road or Sunrise Boulevard, according to California Highway Patrol officer Rich Wetzel.
