Traffic was temporarily shut down on all northbound lanes of Interstate 880 in Hayward after a female pedestrian was struck and killed in the roadway Wednesday morning, officials said.

The California Highway Patrol issued a Sig Alert around 6 a.m. after finding a shoe on the highway near the Tennyson Road off-ramp. Minutes later, officials found the woman’s body and dispatched the coroner to the scene.

The pedestrian had been struck multiple times, said Officer Joseph Fowler, a CHP spokesman.

The circumstances of how she was hit and why she was on the highway were not immediately clear. Drivers were urged to avoid the area as officials cleared the scene and collected evidence.

All lanes were reopened by 8:30 a.m.
