Lanes on University Avenue at Bayfront Expressway shut down for hours on Wednesday following a crash that seriously injured two drivers around 7:30 a.m.
Police said a preliminary investigation shows that a 2002 Toyota, driven by a 57-year-old Palo Alto woman heading east, jumped the median into oncoming traffic in the westbound lane of University Avenue. The car then hit a 2013 Mercedes, driven by a 60-year-old Union City woman, head-on.
The drivers were taken to Stanford Hospital for treatment, police said. The Palo Alto resident remains in critical condition; the other woman sustained serious injuries that are not thought to be life-threatening.
At this time, drugs and alcohol do not appear to be a factor, according to the report.
The Nov. 20 collision remains under investigation. Police ask that anyone information about the accident call 330-6300.
