A four-vehicle fatal crash at 7:25 a.m. today jammed southbound traffic on U.S. Highway 101 just north of University Avenue in Palo Alto.
Emergency vehicles took over three lanes of the freeway, causing a traffic backup that extended north into San Mateo, according to reports. A male was reported killed in the crash.
Two southbound lanes were reopened by 9:40 a.m., and the other lane was reopened shortly after 11 a.m., though traffic is still moving very slowly, according to the California Highway Patrol (CHP).
The CHP reported that four vehicles are believed to be involved, three of which were "severely damaged," according to witness reports. The damaged vehicles were a black SUV Dodge Ram that apparently rolled on its side; a silver grey Toyota sedan that was smashed from both front and back and possibly a small black sedan.
Emergency vehicles took over three of the four southbound lanes, causing a traffic backup that extended north into San Mateo, according to reports.
The CHP issued a Sig-Alert traffic warning at 7:50 a.m., flashing warnings to motorists to take alternate routes -- clogging those streets. The Sig-Alert warning was lifted around 11 a.m.
There were few details as to how many might have been injured in the crash, which occurred at a location known for sudden slowdowns during commute hours.
The silver-grey Toyota smashed head-on into a chain link fence on the westerly side of the freeway, according to one report.
