No stalled vehicles were seen in the area, authorities said, so it’s not known why the woman ran across freeway lanes.

The fatal crash shut down the Nos. 1 and 2 lanes and tied up freeway traffic for miles. The CHP declared a SigAlert at 6:05 a.m., Polizzi said.

The freeway was cleared at 8:46 a.m. and the SigAlert was canceled, he said.
