Police are asking community members to avoid Oxford Street and Marin Avenue in the Berkeley Hills after a collision involving a pedestrian Monday afternoon.
The crash took place just before 1:30 p.m., Berkeley police said.
Police said the pedestrian was still down in the roadway when first responders arrived. She had serious injuries to the head.
BPD has called in its Fatal Accident Investigation Team, which handles serious and fatal crashes, to oversee the case.
The woman was ultimately taken to Highland Hospital for treatment, according to emergency traffic reviewed by The Berkeley Scanner.
The driver, who had been westbound on Marin in an orange BMW, remained at the scene.
She complained of neck pain and subsequently went to Alta Bates Hospital for treatment.
BPD said the investigation is ongoing and that traffic would be "impacted for some time."
A community member told The Scanner that the woman who was hit had been jogging through the crosswalk when she was struck.
In a Nixle alert just after 3 p.m., police said the investigation would cause "traffic backups and detours" for the foreseeable future.
Update, 7 p.m. Police reopened the roadway Monday at 5:20 p.m., according to a Nixle update.
Monday's crash was the second Berkeley collision to leave a pedestrian with serious injuries in just two days.
On Sunday, a woman in her 50s was taken to Highland Hospital with a skull fracture after being struck by a driver in a downtown crosswalk, authorities said. No update on her condition was available as of publication time.
